Smaller tanks overheating in summer?

[Son Of Skyline]

Does anybody with a smaller tank have a problem with tank overheating in the Northwest summers? This will be my first summer with a reef and I want to be prepared so that my 27gal doesn't come to a nice simmer. TIA [img]smile.gif[/img]

I'm from Edmonton Alberta and i had a overheating problem with my 135gal tank. All i did to remedy this was to go to REVY and buy an 8" clip on fan for $15. I clipped it onto my sump and I set it on the same timer as my lights and now my temp never goes above 81 C

I am sorry, but if your tank is getting to 81 C I am afraid it's cooked<g>. We assume you mean Fahrenheit

Clinton, the comment that Bryan was making was referring to the scale that the temperature was being measured in.

Mason, as well as yourself, mentioned the temperature in Degrees Celsius (C) when it should have been expressed in Degrees Fahrenheit (F). 81F would be equivalent to about 26C. If your tank did indeed reach 81C, you would only be 19C short of the boiling point of water, and your livestock would most certainly be "cooked". :eek:

Just a simple error of scale, but important that we all use the correct terminology. [img]smile.gif[/img]

Back to the original question, so nobody has a problem with overheating in the summer?

Mason,

Simon had a great suggestion. get a fan and hit your sump with it. I have two in my hood and if it gets too warm I'll put one on the sump as well. [img]smile.gif[/img] The highest mine will go(I hope) is about 80. I keep my temp at about 78 on average. The fans are how I beat the heat. :D

Speaking of high temperatures and fans....

Temperatures were not a problem with only my VHO lighting as I rarely saw more than 2 degrees difference between morning and evening temps. Now that I have the 250W MH running a few hours a day, my tank temp has jumped 2+ degrees while it's on. I definitely need a hood fan now.

I want a competant but QUIET fan that I can run on the same timer as the MH lamp. I have heard that DC fans are the quietest, but does anyone else have any suggestions?

If DC fans are the way to go, I suppose I could use a regular computer power supply or case fan and a radio shack AC/DC adapter? Is this correct?

PS... Darren, I recall you had a circular cutting bit for a drill for making large holes? If you still do, could I borrow it sometime?

Andrew,

Go as big of a DC fan as you can get in terms of CFM. I am running two 4" right now. But they are no where neear as powerful as my other two. I'll say it again. Get as HIGH a Cubic Foot per Minute as you can find.

AC fans are noisy. But some people can handle them. They move air like nothing else.

Yeah you can borrow the hole saw I have. let me know when.
