Yes, I agree, powerheads are a very decent addition to your tank, I wouldn't say your P would die if you don't have one... But you should have one if your serious about having a complete tank setup.. And I don't hear my powerhead..... at all......importracer;555888; said:Powerheads are a MUST for pygos bra....The current keeps them healthy....Powerheads are their treadmills....But to get the best gas exchange out of any powerhead, place it just under the surface....The more surface area broken means more gas exchange....Beats any bubbler in my book...O yeah, most powerheads these days are near silent.....
