So I'm setting up a 180 gallon display with a 55 gallon sump and was wondering how many 300w heaters I should have in it. I currently have 4 300w heaters to work with. I also have them on a controller, I was thinking setting up 2 to turn on at 79 F and turn off at 79.5 and have a third that will only turn on if the temp drops to 78 and turn off at 79 basically for backup. What do you guys think?
Thanks
