Not even close, first off noone with a tank is staying in the lower tiers of Edison. So if you are running 2x 250w MH lights for 10 hours a day those alone are costing you $50 a month. Then calculate your skimmer, reactor, powerheads, heater, chiller, actinic, return pump, fuge light, controller etc etc etc. Plsu with all that your paying in tier 5 rates so now your TV cost more to run. Its not only your tank that cost you money it now cost you more to run everything in yoru house because your in a higher tier.
