I have my 120 up and running but when i have the lights on the temp goes into the low 80's up to 83.x degrees. I have two 250w halides with spider reflectors mounted inside the canopy. In the tank are two koralia 4's and a mag 12 return pump. I need to keep the temp more regulated so I can move the fish and corals from the old tank into the new one. Is there a way to keep it cool without adding a chiller? Just don't have the cash for one right now. I tried removing the lids to allow for some evaporative cooling but that didn't seem to make a difference. Any idea on how to keep it better regulated. When the lights are off the temp goes back into the upper 70's where it should be.
