I haven't flipped over the res i'm keeping my temps under control and their doesn't seem to be any problem at all. I think i'm just going to throw down the cash for a water chiller. Moving res out of room isn't really an option, my new problem today is my Co2 setup...the tank is about halfway full. when i hook it up to my regulator the adjustable ball doesn't move when i play with the adjustable knob on the regulator it just sits dead at the bottom. I set the ppm to 1200 on the monitor. I closed the tank then turned it back on an it made the ball move once an i set it correctly i just walked back in the room an hour later the ball is back dead to the bottom and the monitor says PPM is 1470 in the room. Does it just kick on when the ppms drop I feel like there should always be pressure there.....
