High Temp.     7/31/17
Hello, this is Kim. In one of my rooms, I have a 29g macroalgae tank. So far it's only growing a baby Snowflake Eel that I'm going to give my friend. The room is decently warm in the summer although it's poorly ventilated, however the tank shoots up to 90 degrees!
<Yikes...>
I installed an air pump, fan, and I point the powerhead up at the surface. I know high temps kill fish because of lack of oxygen, not heat (unless really high).
<A combination of both...
Higher temperature results in both lower/ed dissolved oxygen and higher metabolism>
This only lowered the temp. to 86 degrees and it's been like that constantly.
<Likely okay>
I don't want to buy a chiller as I dropped so much money into this hobby (bought a 700g recently), kind of broke at the moment. However, everything is doing fine, although the eel has been swimming a lot lately. Breathes normal though. Can I keep it at this temp. throughout the summer, or would it be detrimental in the future?
<As stated, you're probably fine. I would leave the light/s off during the day, all the time (even nights) IF it's this warm>
The room cools down a lot after the
summer. Thank you.
<Welcome. Bob Fenner>

Cooling a 24gal Nano Cube  9/11/05 Hey There…  I currently work at Pure Ocean Aquatics in Littleton, Colorado during school.  I decided to go ahead and get a 24gal Nano Cube (small, but fits in my room).  I plan to make it into a reef tank… but I have a huge problem.  My room is over a garage in a house that isn't air conditioned.  My water temperature is reading at 86-88 degrees Fahrenheit. <Yikes...> So far, I've been keeping the lid open, and that helps a little (3-5 degrees), but then I can't have a light on the water (big problem if I want a reef tank). <I'd put the unit on a timer... run the lighting at night, not day> All I have in there so far is sand and cured live rock, so no big hurry.  I want to know if a "Cool Works IceProbe Micro 50W Chiller" is a decent product, <Some folks state so> and if I have any other options.  Also, I need to know how hard it is to set up, and if I should even bother drilling into the glass if I were to get an internal chiller, and so on.  I got a tank knowing water care, and fish, but I underestimated the temperature problem. Sincerely, Ben <Mmm, if you use a chiller for this tank, best to hang the plumbing lines over the side... Try changing the light cycle for a few weeks, and monitor the temperature... cooler weather is coming. Bob Fenner>

Chillin' Out (Is a Chiller Necessary for a Small Tank?) Hi There! <Scott F. here with you tonight.> Do I really need a chiller for a small 24" reef tank in my bedroom that very rarely gets to 24 degrees C? Some fishy people say I do. Others don't. I'm really confused about everything though now! <Confused?  About something in the marine hobby?  Really? hah! hah! Just kidding.  Seriously, unless you have a significant heat problem you could probably do a real good job by using a quality fan directly over the water surface.  A chiller may only be necessary in instances where your tank reaches high temperatures for sustained periods of time.> Anyway, do I need one. They're pretty expensive though and if I did need one could I do a DIY one with a fridge compressor and run the filaments through the tank? That is if even need one!! Thanks for your time anyway.  Bye, Ben <Well, Ben, quite honestly, as above, I only feel a chiller is necessary if you experience a heat problem.  Otherwise, save your money for fun stuff like salt mix, and activated carbon.  Good luck.  Regards, Scott F.>

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: http://www.reefcentral.com/library/reviews/IceProbe/default.htm <Thanks for this. Bob Fenner> HTH, PF

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>
