I have 2 Ebo 250's, a coralife thermometer, 2 250w MH's during the day, Quietone 4000, and a ASM G3 Skimmer pump. At night My temp is at 79.8degrees during the day it is at 80.2 to 80.4 degrees. Nothing fancy here folks. Doesn't matter what time of year it is either. (No house AC either just incase there was to be a naysayer on that fact
)
