Power head

IM thinking about getting one of these for my 40 gallon. I don't want an insane amount of current just a nice gentle current, what would be a good brand and gph? Should I use 2 and split the gph?

Salt or freshwater?

It's ok. Thanks for your reply. I'm guessing you mean 4-5 times the turnover of the volume of my tank?

Yeah. So for a 40 gallon you would want 169 at minimum. For a light flow I'd go slightly higher.
