[jaysauce]

Has anyone calculated the electricity costs for a 250w MH w/ lumatek eballast? I am also running a K4 & mj1200 (For skimmer), and 200w heater.

That would depend on how many hours a day you are running the light. Power prices vary from county to county. You should be able to contact your power service provider or look online for their wattage/price ratio.
