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...
