I am getting a BRAND NEW 75gal tank on friday and I need a heater. Currently I have 1 200 watt heater that I will be using from my 55gal that will have NO inhabitants in the tank. I know a 200W is rated for a 55gal, so here is the question?

Could I purchase another 200W heater to put on both ends of the 75gal tank? Or is this too much? Thanks

EDIT: Tank will be a SA/CA American Tank, kept at 80-82 degrees.

Thats a good question I would like to know too. I keep my 75 gal pretty stable at 80 F with a 200w, but I have had several 200w stop working in my 55 gal. After the last one went bad I put in a 150W I had laying around and it has been doing a good job but I am wondering if I should add one or replace it.

I've been recommending only using 3w per gallon as a rule of thumb for a while now. (Unless the room get below 60F)

So a 200w should work fine.

Rockhaven uses a 250w only and Tangnyasse (my 180g) is using the same.

The "ideal" is using 2 smaller heaters rather than one big one to give yourself redundancy should one fail, and also a single small heater should not be able to "cook" your fish should it stick ON.... Or at least give you plenty of time to catch it....
Two 100w heaters in a 75g would work .
