The PC lighting was less than a month old and NO are about 2 months now. I think 210 watts over 37 may have triggered it with 12 hours of operation. I guess I'll run it with 145 Watts for a while before I make any more changes.
Johnny - My current skimmer is good but water spills are a problem. With frequent power outages the carpets are getting ruined ( I keep my tank in the den). I'll be getting one of those big boy tools kind of skimmer when I move to my 72 Gallon in a month (sooner if someone will take my FW fish from me). I hope the current tank will hold for a month without a skimmer.
