Powerheads

[bellis]

Is there a certain rule or equation I should follow to figure out how much circulation I should have in my tank?

I'm looking for powerheads for my 38 gallon (here: http://www.reefs.org/phpBB2/viewtopic.php?t=74400) and before I did, I wanted to make sure I didn't buy something with too much or too little water flow.

I would add 2 or 3 maxijet 900's. 3x 230 GPH.

I would add a closed loop using a small waterpump (600-800 gph) and a manifold return instead of powerheads. Otherwise, what Anemone said or a pair of 1200's.

Thanks, I'll look into Maxijet. Anybody have anything good or bad to say about Via Aqua powerheads?

I have a couple of via aqua 1800's. They are nice, but I have problems after I clean them. The little black end piece of the impeller's white stick is always stuck way down in there and if you don't get it out, the stick goes in crooked and the powerhead doesn't work. I just broke one of the sticks trying to pry the end cap out and I am having a hard time finding a replacement. But when they are working they are great!
