I'm starting a new saltwater tank...very excited! and I've been looking through the forums for powerhead recommendations (10x tank size) but notice some postings about substrate being blown around. I'm setting up a 40 gallon seaclear rectangle and am confused on whether I should buy 2 of 600's, 900's or 1200's?
Some people say that u can't have enough flow...others say that their current is too much at 10x? So I'm a little confused as what to get. It will be a FOWLR
...at least for now
Thanks in advance for advice!
