When MH and large water pumps come into play Im sure heater wpg rules change.. so.. how do you guys calculate the needed water heater size?
Hara said:All I can say is that I have heaters in the sump and they NEVER come on. Between the lights and the pumps, I get about a 3 degree temperature swing at the most. (your mileage may vary).
Brenden said:I have 4 200w heaters in my sump that have never come on. Definetly get the temp swing down to a minimum before adding livestock. My tank now drops to 77.4 at night and maxes at 78.5 during "lights on". Summer averaged one degree warmer.
