Thanks for the heads up. Fact is we obviously pay alot less than you guys do for hydro. I have done numerous electrical calculators and the totals are much less. I currently am running 5 pumps, 7 heaters, and 1500 watts of light regularly on my coral system and my hydro has only increased about $100/month. My nes system will not require more than 7 times this electricity. IMO it will not be more than 3 times.
I do like SPS corals but will only be keeping them in the middle portion of the tank. This way I can go with 250's around the perimeter and 400's in the middle.
