Yeah, you guys are probably right. The main reason I had opted for the 1000w was because the Pro Heat II line I was looking into jumps from a 300w model to the 1000w model. What I'll probably do is use a 300w glass heater I have now at first, and determine what I need depending on how that performs.
As for the lighting. I'll probably be using a combination of 96 and 55 kits from AH supply. Not sure exactly, but right now it will probably be 2 2x96 kits in the back and 3 1x55 kits in the front. Any thoughts on this? Based on the WPG rule this is 3.1 WPG. I'm a little worried about the height of the tank causing a problem, as it is 28" high. Although my 80 gallon bowfront (26"high) is at 2.75wpg and is doing fine.
