Tankguy and troylee, what kind of lighting do you have? Are your tanks sps dominated? I wouldn't worry as much about the chiller if I was still lps and sofites, but I have a lot more sps.
I have two 250w metal halides overdriven and 250watts if vhos in my canopy... The bulbs are about 8" off the waters surface... The tank is strictly sps I have almost 90 different acros Now lol.....
