Help With Chiller Size/Brand – 05/14/07
I am sure you get a flood of ‘temperature’ questions around this time of the year, so
I will not disappoint.
<<Flood away...>>
I am in the NYC area and I have a 72 bow front with a gravity fed and drained 10 gal refugium with 4-inch DSB and a 20 gal sump, with a  Mag 7 for the skimmer and a Quiet One 4000 HH for a return.  I have a single Iwaki 100rlt pump powering a closed-loop manifold, and a Current USA Outer Orbit setup running 2 x 150 watt metal halides and 4 x 54 watt T5’s.
<<Ok>>
The temp is floating around 81 and maxed at 83 before I shut the metal halides down around 4 pm.
<<Not a problem in my opinion...and is about where my system ranges>>
My major concern is that it isn’t even really hot here yet, and the room the tank in doesn’t hold air conditioning well.
<<Ah, I see>>
I have a 6-inch fan blowing over the refugium and another blowing over the surface of the tank and it seems to be doing ok for now, but I think I see a chiller in my future.
<<Mmm, yes...maybe so>>
I am trying to figure out what size will be able to handle my tank without constantly being on.
<<Probably best to go by manufacturer recommendations...and if you have the cash/want the extra capacity, get the next larger model even>>
I have checked the JBJ site that has a calculator for just such a thing and it is saying the ¼ chiller, but reading the Wet Web FAQ I have seen a 1/5 being suggested for an 80 Gal. tank.
<<Indeed...  I employed an inline (more effective than the “drop-in” style of the same size I feel) 1/5hp chiller on my previous 80g reef and it was plenty large enough>>
Also I am torn between brands, do you have an opinion on the Current USA chillers?  I am leaning towards either a JBJ or a Current USA, any other suggestions?
<<I own a Custom Sea Life (CSL) chiller which has performed flawlessly for more than five years.  CSL is “no more,” but I believe the product line was taken over by Current USA and thus the chillers they offer may well be the same as the old CSL models (Bob, please correct me if wrong).  As for another brand, the Aqua Logic in-line chillers are a good choice>>
Thanks,
Randy

- I am in Need of Answers!!!!! -
Good morning Gentlemen,
I stumbled across your site while researching prices for accessories for my new salt water hobby. I read the various questions and answers and I found your website to be very informative. However I am going to purchase your book so I can learn more about the salt water hobby. I am transitioning over from fresh water with over 10yrs experience and I have found that everyone has a different opinion about what is best "product" especially if they are the ones selling the product. <Quite true.> This is my question.
I am purchasing a 150 gallon reef ready tank. I don't know which skimmer to use. I heard a lot about the Euro Reef and I was told to purchase the ETSS 600 skimmer. I did see the sump I was going to purchase which was the UHF Sump 72 system by AETECH. AETECH had the complete sump and skimmer setup on their site. I need your opinion as to which skimmer/model to purchase for the size tank I have. <I'd go with the EuroReef.> I will have live rock etc. I am going to have North Dallas Aquarium to maintain my tank as I learn more about the hobby. Also what do you think about the JBJ chiller? Which chiller would you recommend? <Have no practical experience with chillers - know that some are crap, but not entirely sure which ones those are. Best to look and ask around on the forums where you're likely to find several people using chillers.>
Please reply to my personal address so I won't miss what you have to say. I greatly appreciate your help.

Chillers
Hi,
<Hello there>
Has any body used the “Pacific Coast CL-280 1/10 HP Inline Chiller” or “Arctica Titanium Chiller (1/10 hp)”.
<Have seen these, not used them>
I need to purchase a chiller soon and I could not make a decision between these two chillers. Arctica is little bit more expensive then CL-280 but that does not matter. I have some info about the Arctica Chiller but I could not find any detailed info about CL-280. I need a good chiller that can hold the temp and not fluctuates all the time because of the room temp.
Currently I have “Teco Micro Chiller”, which I had for 1 ½ years and right now it fluctuates between 76F in the morning to 83F in the evening.
<... this is too much>
Actual water temp is between 76F to 81F. It used to be better but it is getting worse every day. I cleaned it every three month but it does not make a difference, my fishes are stressed out every night.
<I'd write the manufacturer here... there may be some user-friendly repair...>
Please help me to decide. I will need to order one soon.
Thanks,
Hans
<With such gear issues it's best to "cast your net" far and wide for input. Try posting your question, lurking for others inputs on the BBs like ReefCentral, Reefs.org... to get a survey of actual users, other possibilities. Bob Fenner>

Reef Recommendations
Hey Scott ("Captain"- what's that all about please do tell?),
<Really bad "Star Trek" reference....>
Again, thanks for your recommendation and prompt response. Do you think that I may need a Chiller, or can I get away with fans with 2X 250 watt HQI's?
<Honestly, I think that a chiller is a really good idea. You can try the fans, but that's a lot of heat put out by those bulbs in a small space, so a chiller will do a better job.>
I do have a Canopy, what brand should I buy?
<I'd look into the JBJ Arctica chillers. As far as MH systems are concerned, there are so many different brands to choose from...Consider those made by Aqua Medic, PFO, and Sunlight Supply. All are good ones.>
Thanx, Marlon
<A pleasure! Regards, Scott F.>

Chiller and Filter reviews 8/2/05
Anthony, Thanks for such a prompt response.  I will review the website you mentioned more thoroughly, One of our consultants on the Sitka aquarium is a biologist with the Dept. of Fish and Game who maintains a tank for the elementary school.   
Hopefully his input will keep us within any specimen collection regulations that apply.  I don't even know what a Cnidarian is, but will quiz Troy about it.
<Sparing you the google search for definition... this is the group of stinging organisms that include corals, anemones, polyps, e.g..>
BTW, have you completed the review of the TradeWind chillers?  
<I have indeed reviewed and critiqued the unit... the construct and operation are very fine. I am sending along suggestions for improvement on their product brochure for clarity>
We are looking seriously at that particular unit, but would love to read your review before committing to such a purchase.
<Seem to be made very well... so far, reliable operation with not the slightest complaint. Indeed..
there is some noise and heat with most any chiller. This unit is not especially bad about either at all>
Any reviews out there on Jeff's Berlin Lifereef sump system?  
<None that I have seen>
It is expensive, but it looks like a well designed, thought-through unit. Kris
<I'm not one for over-engineered designs (DIY or otherwise) for what is or at least should be simple components of the system. FWIW. Anthony>

Chiller recommendation 7/30/05
Just wondering if you guys could help with a chiller recommendation.  We've had a reef tank for 7 years its approximately 160 gal ,metal halides (2) and lots of pumps
Our 2stage  inline chiller is not working properly anymore, and we need to make a decision soon.......
<I strongly favor inline (never drop-in) for efficiency, and am very happy with the construct and performance of my Tradewind:
http://reefcentral.com/forums/showthread.php?s=&threadid=597821&highlight=chiller
Also what temperature would you consider optimum for a reef tank with some fish as well?  
<I like 78-80F for tropicals Best regards, Anthony Calfo>

Temperature Control in Reef Aquaria  12/17/05
Hi Adam, I need your advice again.
<That’s what I’m here for, hello again Jerry.>
The Outer Orbit lights work great!
<Glad you like it.>
But my tank is now running hot 82.4 degrees with room temp of 72 degrees. I was looking at Pacific Coast 1/10 chiller or Artica Titanium 1/10 or Current/Prime 1/10. Any thoughts on these brands or size on a 125 Acrylic.
<On a 125 I would go with at least the 1/5 or ¼. Smaller chillers seem to be perpetually “ON” and thus even though they are smaller, end up using a lot more energy. As far as brands look into the Titanium Artica made by JBJ.>
(120# live rock, 4" sand bed, unknown size wet/dry sump, Top Fathom Skimmer and Little Giant 4-MDQ-SC rated at 810 gallons at 3feet). I do have air conditioning for the house in summer but we usually set it at 78 degrees so I'm thinking a chiller is needed.
<Also consider some fans blowing across the surface of the sump or display.>
Could I use the sump/skimmer pump for the chiller?
<You can, personally I didn’t want my return pump being obstructed by other media (I wanted to get the biggest “bang” out of it), so for that reason I used another pump to put the chiller on a closed loop.>
Should I place the chiller in the stand or mount it on the basement
wall below the tank?
<They are VERY noisy, place it as far away from you as possible, I keep mine in a shed outside.>
Thanks again for your help, Jerry
<No problem, Adam J.>

Sizing A Chiller - 01/21/06
Hello WWM,
<<Hello Mike>>
This is my first post on this web site and hopefully you can help me out.
<<I'll try>>
I have an 80 gallon saltwater fish tank and will be getting coral soon.  Basically my setup will be two 175 watt Hamilton MH and maybe two 65watt actinics, mostly LPS.  They will be about 12 inches off of the water and I will have 4 fans in the canopy.  My water temperature got to about 88F in the summer so I know I will need some sort of cooling method.
<<Mmm, yes...a bit high.>>
I was looking at the 1/10 hp JBJ Arctica or the 1/10 hp Pacific Coast chiller.
<<I fear these will be too small for your system.>>
Will this be sufficient enough for my tank?
<<No>>
If not what do you recommend?
<<I was able to keep an 80 gallon in-wall tank (w/2x 175w MH) cool with a 1/5 hp inline chiller...should also work for you.>>
I'm kinda on a tight budget.
<<All the more reason to get it right the first time.>>
I also know someone that is selling a 1/4 hp JBJ chiller but not sure how old it really is.  I doesn't say JBJ or Arctica anywhere on it.  Was it not always called that?
<<I can't say.>>
It says something like fish cooler.
<Hmm...>>
He is selling it for $375.  He said that it's about 1 1/2 yrs old.
<<Well Mike, would depend on how well you know this other chap I suppose...is up to you... but for a little less than $200 more you can get a new (and under warranty) 1/5 hp Arctica chiller...something to consider.>>
Here are some photos.
<<I couldn't get the photos to come up.>>
The help is much appreciated
Mike
<<Regards, EricR>>

Chillers, Absolutely Quiet…..Only When Off  - 5/7/2006
I have a 75 gallon salt water aquarium in my living room.
<Cool.>
Would you please give me a list of chillers that are reliable and are SUPER  QUIET.
<Hmmm, well my friend, chillers operate much like a refrigerator, yes some are more more reliable and quieter, better if you will, than other but none emit zero noise. My solution was to construct a cabinet for my chiller out of 2” Thick Solid Teak and line it with “weather-proofing” material, anyways here is a list of favorable chillers:
**JBJ Artica (This is what I use)
**AquaLogic
**Pacific Coast
**Teclima
**Aquanetics
Check those out…>
The chiller that I have had for the past six years has been  reliable but is noisy.
<They are all relatively noisy, especially in larger models, another thing with chillers is that small unit are always on because their cycles last longer, larger, over sized units will stay on much shorter because they don’t need as long a cycle to cool the water.>
Thanks for your help.  Dennis  Rohrer.
<Anytime, Adam J.>

Peltier cooling idea  11/22/06
I last sent a post, Tank cooling prob.s  9/29/06
I have given up using Freon type cooling as it is too expensive on the power bill.
<Mmm, only one of quite a few technologies...>
If I get lucky and am able to find a 12volt Freon car fridge I will certainly use it.
<Well... these have dismal efficiencies...>
I have recently found four Peltier
<Ahh: http://www.heatsink-guide.com/peltier.htm>
TECs and some thick (6mm) copper sheets and thick copper wiring I will use as a porcupine heat sink for the Peltiers. These Peltiers were taken from old car fridges that run on 12vdc, 10amps.
<Yikes... more than a tenth of a kilowatt per hour... if they run continuously, more than 2 kw per day each... In California and HI (where I'm most familiar) this would come out to more than fifty cents per day... per unit>
The power supply I use will be 2 ATX power boxes used in computers and are capable of 400w at 240v, outputting 12vdc at 10amps under load with one ATX box running two Peltiers. My experiment in cooling 2 litres using just two Peltiers was proven successful as the Peltiers cooled the water from 27 degrees centigrade to 12C in under an hour using only aluminium as a heat sink and cooling element. My problem is that I need a non-corrosive barrier between the cooling side of the Peltier and my salt water sump.
<Yes... likely a thinner (thermally) tubing of determinate length, immersed in a/this liquid bath... a pumping source to recirculate the system water through this tubing>
To maintain direct cooling efficiency, with minimal power consumption, I have decided to go this way instead of the insert plastic tubing into cold water method.
<Mmm... okay>
I have seen on EBay some sheets of titanium that may do the trick for this barrier I need between the cooling Peltier element and the saltwater I want to cool. Is titanium totally uncorrosive in saltwater or should I be looking out for percentage of titanium relative to impurities added.
<Pure/r Titanium is used as jacketing in many consumer/commercial coolers...>
At the moment I am looking at onlinemetals.com and they have titanium grade 2 at 99.3%Ti and the only major impurity at 0.3% is Fe (iron). The thickness is just over 1mm and it is 12x12 inches as a sheet.. What are your thoughts on this crazy idea?
<Well... I would still use the immersion bath, tubing transfer method... in an insulated container myself... The cost of the Ti, welding... is too high to suit me... but a worthwhile adventure for sure. Bob Fenner>

CHILLER QUESTION
Hi there, Bob
<Howdy>
Sascha here with a quick question, Custom Sealife chiller or Aqua Logics chiller, they are about the same price, but I like the size of the Custom Sea life better and I know you like the Aqua logics. Should I get drop in or inline for my two connected systems??
<Definitely in-line and I would choose the CSL unit>
My new tank is coming in 3 weeks(190g corner tank) and I love shopping. 
<I as well>
So my total water volume should be around 330g for both systems combined through wall) and I'll get the 1/3 hp.
<Hmm, well... what's the "draw down?" How many degrees from ambient do you think you might want/need to lower the temperature? Take a look at the Aquanetics site (link on WWM) at their chart for this purpose... the tanks are in your business near the coast? Is the room itself air-conditioned all the time? You might want something more like a half HP>
Thank you again and don't forget to come for a haircut, hahaha.
<Don't laugh or scream... the wife took my old Wahl clippers to try and straighten up what I'd wrought... can't stand to lose too many more handsome or style points>
I am looking out my salon window everyday for a guy in a fish shirt and a hat.
take care and good to know you are always there to help

Nano-reef chiller
Dear Mr. Fenner,
You were very helpful in a previous question about a ten-gal nano reef skimmer. I have another question for you. I live in Hawaii, home of the coral reefs. Unfortunately, the temp (even with evaporative cooling) has been noted in my freshwater ten-gal at 82, 84, and even 86 degrees. I assume I will need a chiller for my new saltwater 10-gallon. There is a product called the CoolWork's IceProbe costing $100. It is a micro chiller that uses a cooling probe inserted through the bottom of a tank. It has been designed for approx 10 gal aquariums, and the manufacturer says that it "directly converts electricity to cooling power". Have you ever used this product, do you recommend it, and should I get one (or some other chiller)?
Thank you very much for you advice
<I've seen this product at a couple of trade shows (the business side of the pet-fish interest)... am concerned about the lack of a controller (you can buy, make one) with this "continuously on" chiller on such a small volume of water. If you do intend to use this unit, do secure/use a controller. Bob Fenner>

Nano-reef chiller
Hi Bob,
PF again throwing in my spare change... ; )
RC has an article about using one of these Iceprobe Chillers in a HOT filter. Given that my lighting pushes my temp up to 84F(and probably over), and the fan I have to cool it blocks off the view of the tank, I think I'll be doing one of these myself. here's the url:

Custom Sealife vs. AQUANETICS Chillers
Looking for a personal opinion...Custom Sealife vs. AQUANETICS Drop in Chillers which is better for saltwater and why?
<drop in chillers are very limited in their scope of ability (pull down from ambient versus flow thru... I personally would avoid all drop in styles for a more efficient flow through style if at all possible! The plumbing for a flow through is ridiculously easy... I see little trouble for most people. Besides... a drop in further requires that the unit be near the tank display that needs cooled down; what an incredible waster of energy for the heat they produce in the same room that requires the tank be cooled down! And all chillers are ideally mounted/plumbed from a remote room where the heat generated by the chiller is moot>
Duplex stainless steel vs. Titanium
<Titanium will outlast/outlive stainless steel in most every application. Best regards, Anthony>

Chillers
Greetings Bob
I have a quick question for you. I have a 55 gal reef. I am having problems with temperature and am looking in to a chiller. Have you or your cohorts heard anything about the "Ice Probe Thermo-Electric Chiller"? The price is hard to beat but is it worth it? Please pass along anything you may have heard. 
Thanks in advance.
Ron
<I have seen this unit at a few trade-shows in the last few years, but never used it. According to its re-sellers it is capable of a draw down of 20 degrees F of ten gallons in an insulated container... Not much of a pull... as your system is much larger, not-insulated... but for only a 50 watt power consumption, and maybe you're only looking for a slight thermal reduction... it might be worth trying. Otherwise, a simple "fan blowing across the surface" of the tanks water would likely produce the same reduction. Bob Fenner>

Re: Calcium Reactors in Australia (and expensive chillers!)
Hi Bob,
I have placed an order for the Dupla reactor and now keenly await its arrival.
A piece of information that I thought you might find of interest and perhaps Diana as well. I asked the supplier of the reactor about the availability of Korallith media. He informed me that he had tried to access it but Australian quarantine forbids its importation (do not know on what basis, now making further enquiries). Could not see how it Ca reactor media would pose a risk, but our country has some pretty tight restrictions.
<Me neither... will forward to Di and Ralf and Daniel in Germany>
I have another question for you, this time about chillers. I am planning to install a chiller on my tank before this summer season. Our average maximum temps for about half of the year sit at around 35oC. Not the ideal climate to live in for a mini-reef enthusiast. In the past I have air-conditioned the room but relying on an air conditioner (on a timer) for 14 hours a day 6 months a year is a bit much. With a chiller I should be able to reduce this significantly to just the hottest part of the day and the middle summer months. Having the two units together when we are away is also a better fail safe.
<Sounds like a good plan>
I have been trying to do some research on brands but have been able to find out little about the models available in Australia. My options in Australia are
- Teco Chiller/ RA680 will cool 800L by 10 degrees C below ambient room
temp. Cost $2020 complete with thermostat. Italian Made (I think).
<Yes, a good unit>
- Sfiligoi Chiller Big Flite will cool 750L by 15 degrees C below
ambient room temp. Cost $2100 complete with thermostat. Italian Made.
<Also an allegedly well-made unit>
- Resun 0.6 hp chiller will cool 750L by 12 degrees C below ambient room temp. Cost not sure but assuming $1800-$2000 complete with thermostat.
Asian Made.
<Don't know about this product>
- Aquasonic Aqualogic chiller 1/3 hp will cool 700L by 7-8oC below ambient room temp. Cost approximately $2000 complete with thermostat.
<Yikes... even with the improvement recently in the Austr. dollar?>
All units come with a 12 month guarantee.
My question is which one??????
My system holds about 700 litre and has Halide lighting (another source of heat). My preference at this stage is for the Sfiligoi Chiller Big Flite due to its cost vs. cooling capacity. These units are normally $2600 but the agent in Australia has a winter special at the moment for $2100. The components in contact with water in this unit is 316 stainless steel which I am told is completely safe for marine aquaria (not sure about this anti-corrosion claim). The Teco which would be my second choice at this stage has platinum (I think) components but has a less cooling capacity than the Big Flite.
<I agree with your choices>
I have not been able to find much information on any of these brands apart from manufacturer specifications that all claim their unit is the biggest and best for aquarium use (how could they claim anything else?).
Teco are common in Australia and apparently reliable. I have been told by one dealer that Resun were junk (he is selling other brand of course). I think Aqua medic may have a brand available but the cost is much higher than all the other units and only have same cooling capacity.
So I am at a loss as to which one? It is a lot of cash to shell out but given our climate, the value of my livestock and the expense of running an air conditioner and fan which is only a stop gap measure (tank still goes up and down by 3 degrees in summer 25.5-28.5oC) and if the timer or air conditioner ever failed (real possibility) I would lose the whole tank. I tried a couple of DIY projects using an old freezer and then a fridge both were ineffective.
<Agreed... not worth the time, trouble in your sort of setting (draw down, volume, type of system>
However I don't want to buy a brand that is junk or will die within a couple of years.
Which brand do you suggest? Is the Big Flite any good.
I look forward to your comments. It is really fantastic that you make your experience available to fellow hobbyists. Much appreciated.
Cheers
Paul Grundy
<Paul, do try the various chatforums in your part of the world, get a take on the actual experiences of end-users/consumers. Ours: http://WetWebFotos.com/talk/ won't likely have folks with experience with these makes/models, but worth a try. Bob Fenner>

Chilling Out!
Several Months ago in summer, I purchased an Aquatherm Chiller/Heater from Flying Fish Express <<Now out of biz.>> thinking it would maintain the chosen temperature of 77 degrees F. by merely setting the thermostat to same and it would switch as necessary between heat and chill automatically. No, you have to manually change it over several times a year depending upon the ambient temperature. Is there such a device made and finally what is your evaluation of the Aquatherm in comparison to other brands?  Thank You for your valued advice and opinions. Stephen Pace.
<I personally have no experience with the Aquatherm brand. You may want to post on the wetwebmedia.com chat forum to get your fellow hobbyists' opinions on the product. I have used the Medusa dual stage temperature controller with good results. plug in your heater and chiller to the unit, and set the desired temperature. The unit energizes either the heater or chiller as needed to maintain the desired temperature. There are other manufacturers making this type of unit, too. Do check our sponsors' web sites for availability and pricing. Good luck! Regards, Scott F>

Just Chillin'...
Does anyone have any real experience with either the Artica chiller by JBJ, Premier Chillers, or the Aqua Medic chillers. I am probably going to need a new chiller for my 500 gal. reef tank. Noise is DEFINITE consideration as my wife hates any noise coming out of my aquarium room.
<I can understand that>
Am considering a 1/3 or 1/2 hp chiller.
<I'd go with the 1/2 hp>
At present, I have a 1/4 hp West Coast Aquatics chiller which is about 11 years old. I replaced the compressor about 7 years ago and is now starting to give me cooling problems again. Live in Houston, summers are tough, and my temp. is starting to get to 80 degrees with metal halide and compact fluo. light on daily. Price on the Aqua Medic and Premier chillers seem rather cheap for the 1/2 hp compared to Aqua Logic. Any info. you might have will be appreciated. Thanks, Harold
<Well, Harold, I have not had personal experiences with either one of those models. I'd put out a post on the WWM chat forum to see if any fellow hobbyists are using these units. One caveat, of course- the least expensive model is not always the best one. Since your chiller is an important component of your system, you need to make sure that it is a reliable one, with a good long-term track record. Sorry I couldn't provide more specific information on these units, but I think you get the idea! Good luck! Regards, Scott F>

- Chiller? - Iceprobe
Hello Guys,
<Good morning, JasonC here.>
Great site, I have learned much and have a very successful 55 reef tank. <Glad to hear it.> Much of it due to your help.  Deep sand bed, frequent water changes etc.  I digress. I am a bit concerned about the heat of my aquarium.  Are you familiar with a product called cool works ice probe? <Yes.> Look a bit gimmicky, but I don't need too much help, just maybe 4-6 degrees in a 55 gallon tank during the day. <I don't think this device will do it for you on a tank of this size.> I was wondering if it is a useable product. <On much smaller tanks, yes.> One more thing, I would like to install it into my refugium instead of my tank itself.  I have the 18 inch CPR hang on, and frankly would rather drill into that than my aquarium. <Do-able, but not advised... again, consider something a little larger - there are other, larger chillers on the market now that use the same thermo-electric devices as the Ice Probe and are capable of handling a tank of your size.> Any suggestions would help.  Thanks.
<Cheers, J -- >

Chilling, chillers
Dear Bob,
<Howdy>
Please allow me to apologize for my far less than friendly attitude expressed in my first email to you.  One of my many faults in getting angry  when I am frustrated.  I do have the means to contain myself.  Like a computer, garbage in , garbage out.   
<No worries>
     An WWM article some where  mentioned the word 'tidepool'.  This is as close as I have been able to get to the topic on the Web, or the library.  I guess I will have to think reef, and make adjustments. The problem with the chiller thing, is it's a deal breaker.  Sort of pumping salt water round and round through the filter, I can't get started without one.  Don't have a tank yet anyway, too many questions.
<Good to have>
      My attempts to get to 'ozreef.com'  have not been successful.  Is there more to the URL?  Am I looking for apples in the turnip store?
<Sorry re. The URL is: http://www.ozreef.org/>
  1 HP = 746 watts, but  how much cold, daaahhhh.  BTU = 1b of water  changed one degree F.  Will I need to know more?   Folks selling tanks plus gear are offering 1/6 HP chillers with 75g tanks. No good?  I think salesmen are the wrong guys to ask, but don't know the right guys.  If  I
<Do see the chart on Aquanetics chart: http://www.aquanetics.com/pdf%20files/fluid_chiller_asc_adic_1-4.pdf>
could afford to pay, a refrigeration engineer, I could buy a chiller.  Fish store guys with 75 degree livestock know I will be buying very little from them. I will have to make my own live rock and sand.
<And livestock too?>
Your living accommodations  sound like what I grew up in.  People with the garage doors  live on the lake. They may own chiller companies.   If titanium can be welded to copper,  I can find someone to do it for me.  I will be farming out several things I don't know squat about.  
<You are wise here. No welding these dissimilar metals as far as I know>
I caught tidepool mini monsters as a child, and took them home in a can, they died. I shot a bird with BB gun, it died.  That's enough great white hunter for me.  To keep them alive and 'happy'  is a better goal.  Leaving them  where they are is a higher goal,  but gee whiz Mom, a guys  gotta  have somthin' to do.  
<Yes... to err as in to wander/wonder is human... many other possibilities... making pictures, writing, telling stories...>
Any thoughts about reliable methods of keeping  100gal of water at about 60 degrees forever would be greatly appreciated.   Thank you,  and thank goodness for WWM.com
<Really, the only consistent, reliable method (barring a thermal sink in areas where the ground is cold year round) is to employ a compressor type expansion, heat exchange... chiller unit, with a thermostatic mechanism. Bob Fenner>

-Mystery chiller-
Hello, I have a product question. I have a chance to buy a 1/3HP for about $300.00. <Whoa, that's pretty cheap> A friend of mine has to sell off all his fish and supplies because he owes people money. Don't take up gambling, could lose your fish. <Haha, made a mental note> The only problem I have with this chiller is that I can't find anything about it on the internet. It says TUNG.FA on it and it is a model TF-400B. I was wondering if you have ever heard of this. <Nope, never. I had no luck on any forums or search engines.> Didn't It is brand new still in the box. It comes with a controller. I think he also said it was a chiller and a heater. Mainly want to know if it is quiet. <There's no instruction manual? I would buy it, if it's the appropriate size. It is also important to note that all chillers are loud, especially larger ones like this. I hope this helps, somehow! -Kevin> Any help would be greatly appreciated.
Thanks
Marty

Chiller vs. Fans  8/30/05
Hi, I have a 100 gallon aquarium with a 30 gallon sump. I would like to replace my fans with a chiller. Without the fans, the aquarium can easily reach temperatures exceed 90 degrees. With all four 12" fans running on high 24/7, the temperature stay at 78 degrees. So the chiller would have to be able to drop the temperature about 15 degrees. Maybe a 1/4 hp chiller or perhaps a 1/3 hp?
<The one third... better to have a bit more chilling capacity than too little>
Also, I know that some brands are more efficient so some 1/4 hp chillers might cool better then some 1/3 hp chiller.
<Yes>
I also need a quite chiller so if you could recommend one for me I would appreciate it. Thanks, Andy
