i am having trouble finding the right powerhead...
i am setting up a 20 gallon frag tank and want to have 4 powerheads in it.yes, 4, as i want nice flow but dont really care for looks as it is not a display.what would you reccomend.

I like the Aqua Clear Brand because reverse flow option and you can get a quickfilter attachment for it.
I have been told though that Maxijets are the best......

the zoo-med powersweep all the way

Maxi-Jets are some of the best. Decide if you want the 900's or 600's.
