Scott - you have to remember that Krish is in the Bahamas, though. You'll find out about mid summer when our temps get really high, how your tank does with its new lights. We are still pretty mild right now, and I don't even need my chiller on yet. It makes a difference, even when the A/C is on. Krish's climate would probably compare to our nasty summer humidity and heat. I'm not saying Krish has to get a chiller, and I hope the few things he has left to try do work. I'm just saying it is hard to make comparisons on your systems being similar, when the climate they are in is so different. Once you have your new lights on the tank through the summer, you'll be able to make a better comparison. Make sense?
