water chiller

I have a 20 gallon tank with fish and corals. I need a chiller for it, the temp is going up to 82-84 any ideas?

 

I just popped a fan blowing on my water surface, that took me down from 86 down to 78.

 

A clip on fan from Wal Mart works wonders, you might even need to put the fan on low speed and on a timer to keep from cooling things off too much.

 

awesome thanks guys

 

wally world fan worked great thanks for the help guys

 

Old computer fans worked for me I attached them to plexiglass and put over my sump took it from 84-85 to 78-80

 

Its crazy how a little evaporation can cool things off so much. Takes a lot more topping off but much cheaper than a chiller or setting the house AC down lower.

 

water temp went from 84 to 76 the fan works awesome

 

I have a JBJ 1/15 chiller that I just bought, ran for a month and stopped using. If you want it let me know. I'll make you a deal you can't refuse.

 

What lights are yall all using? Also what temp is your air conditioner set? I'm looking to keep mine in the lower 70's, but rather not have my AC low with the electric bills going up and up lately.
