heaters?

[Kitteness]

which heaters do you guys use on your big tanks? just one or multiples?

 

[polywise]

if you can, it is safer use multiple heaters. rate at 3-5 watts per gallon.

I heat with 3-400 watt MH and for back up I run 3 300 watt heaters all on separet controlers.

Currently I have two 250 watt heaters in my refugium for my 125. I will most likely add two more when I transfer to the 240.

On my 600gal display (96x48x30) / close to 1k total water volume I will be using 2x controllers and 4x 500w heaters...
