HOW DO U KEEP YOUR TANK COOL?

[Lance]

With A/C and fans blowing on the water surface, I never have a problem.

Another thing you can try is changing your photo period so that the lights are off during the hotter part of the days.

I have a fan blowing and a titanium coil in my sump, the water runs from my cold water line into my RODI filter system. The solenoid is controlled by my AC3 controller and it lowers my tank's temperature and increases my RODI output.

In the winter time, less evaporation and the water output is less and in the summer I have more evaporation from the fan blowing but matched up with higher water output. It's cheaper than running a chiller and I have to replace the solenoid every 12 months or so but that's only $30 and no energy consumption.

However, this needed to be well planned out or you'll have more trouble dealing with floods!

I have my 120 G with 2x 250W Metal Halides and T5 in the basement (which of course is cooler to begin with) and I use nothing to cool the tank. My temp fluctuates from 78-81 (Max) and thats it. I have found that having a halide free period for an hour in the middle of the day allows the tank to cool down slightly and has actually helped.

i have a $10 clip on fan from walmart over the sump, and pieced together a 4 fan system with monitor for the hood for under $200 (all computer stuff)

Aviators...

Nothing looks cooler.

My tank is in the basement, never had a problem with the temp staying where it should be. A couple of fans will work well though.

Fans blowing across top of tank. Central AC. HRV to control the insane humidity.
