cooling a tank

[Neil Woodman]

Does anyone have a relatively inexpensive way of cooling down your
tanks? I plan to be using a small tank with MH lighting but I cant
particularly afford a chiller right now. Short of positioning a fan
blowing at the water surface to take the heat away can you guys
recommend anything else? My house gets quite warm in the summer and its
hard to keep cool, my tropical tank is at 30c at the moment and I've
just turned the heater off because it wont cool down at all!......Maybe
I should start keeping discus...

I experimented a few things for my tank, as the water was around 82f. I
placed a fan in the hood, I left the hood open with a fan in it.....anyway
the pace that did it for me was placing a fan over my sump area in the stand
under the tank. It dropped the water down 3-4f. Do you have a sump in the
stand? Maybe someone else has some ideas?

I had a small tank with MH, a fan was all I needed.

Neil,
I am not sure if this is feasible with your tank, but the way I did it
with my tank was to use a fan in the hood that blows air across the
water surface.
I had to actually design a thermostat that would turn the fan on only
when tank temp reached 78F (~25 C) from 85F.Without the thermostat it
would drop down to 74F.

I use fairly expensive fan though - Dayton 6kd75 ($36 Grainger.com)
....

Here is the link to simple thermostat schematic. This is not the one i
use but very close functionally...

Hope this helps.
