I have a 60 gal reef tank. I currently have 4 96w CF bulbs (2 White and 2 Act). I am changing to 2 250 w MH. I've been using the room AC to control the tank temp but it fluctuates about 3 degrees thoughout the day. I am going to put a chiller on it but I wonder which one would be best.
Any suggestions?
