Heater capacity

[new but handy]

hey I run 3 250ws on my 235ish sys I should probably get one more but spring is coming

I only use 2 300w on my 300gal but then it is in a small enclosed room that maintains the temp quite well. I am using a Medusa temp controller and I rarely see the heaters on. Temp runs a pretty consistent 77.8deg.
