Cooling Tank Without Chiller

Reversing your lighting schedule and running large fans across the water surface will do much more than floating ice packs. Surprising how well the fans work.

With the temp in my office @ 81-85, the one 120mm fan keeps the QT cool
Lots of evap, but it works just fine

Got home yesterday and tank was a nice 84 degrees, in a 10g nano it's a pain in the a$$ to keep the temp Down, but I put a huge fan right beside it and so far so good. My green bay packers zoas took a hit though they are closed and look like they are melting away

im running all LEDs. they dont put much, if any heat into the tank.

Same here. When I had a heat problem before LEDs I would turn the ATO off and take an icecream pail of actual tank water out and freeze it. Than put the big ice cube in the sump. Rotated 2 buckets like this and it worked good for me.

Indeed.

I've had good luck with pointing a small fan at the top of the tank to move the heat away from the Halides, and evaporate water =)

I've also been using cold water for top off

I agree with the fan. I blow a fan across the water surface and my temp. drops 2-3 degrees, lots of evap. though.
