As far as equipment, I kept it really simple. I hear to many horror storys about the amounts of money that people spend on there power bill because of their tank and I really wanted to stay away from that. I have an 80 gallon sump/fuge (2-40gallon breeders). Not sure what the return pumps are but nothing great. I used to run a hammerhead return but it was pushing a constant 400+watts of power. I decided instead to go with tunze powerheads (2-6201's and 4-6101's) on a 7095 controller. Im running a medium atb skimmer with the upgraded airstar pump (another huge energy saver). No calcium reactor as of yet but looking to get the geo 818. With the depth of the tank I did decide to use 3-400 watt mh, and 8-4ft t-5 actinics. Like I said I built this tank with the power bill in mind. I spend on average 150.00 for my entire house including the tank. I will post some pics of everything else soon.
