This is my 55 gallon community tank. I decided to go back to my Aquarist roots after taking down my Mbuna Cichlid set up to install new flooring.
Biggest hurdle for this is water temperature. Here in steamy Florida, it's difficult to keep water temps down in the mid 70's when the house goes up to 83* during the day while we're working. I decided to modify my traditional hood set up to accomodate an evaporative cooling system to keep water temps down.
What I've done is remove the fluorescent top fixtures, then remove the glass the lights sat on. I replaced the glass with grating, then installed a cooling fan on each grate, that is controlled by a rheostat. The idea is to blow air down on the water to increase evaporation, causing water temperature reduction.
Here's the particulars:
55 Gallon tank
Cascade 700 canister Filter
Whisper Air Pump 60
(2) Cooling Fans with speed controllers
(2) 17 inch LED Clip on Light strips
Here's the left side of the tank cover viewed from the top:
Directing the filter wand to agitate the surface of the water under the grating does create some cooling without the fans. With the fans running on low, the water temperature can be dropped to 75* with the room air temps between 78 and 83*. The heater prevents water temps dropping below 75*. I'm currently working on a temp switch to control the fans, so I can rely less on the heater to regulate tempurature.
Water stays within 1* variance (average about 6/10 of a degree). Evaporation is about a 1/3 gallon a day. This has worked out great so far, and I'm pleased as punch with the end result. Fish seem happy.... I'm happy. It's a win, win!
