i thought the same thing.....i picked up an ac (801) which is an ac70 where i come from, so as mentioned by 2p2f that would be a suitable one for your tank...i thought mine was going to be a waste but my fish swim in it all the time, it would be a good pick up, and helps out with water circulationHaha I got more replies about the filtration than the powerhead...so do I really need a powerhead at all?
My pygos sleep at night.I keep most my ph's on a timer. Throughout the day they may turn on 20 time, but only do so for maybe 5-10minute at a time. I dont have them turn on for any serious amount of time till just after the lights go out with almost every piranha is most active. I find that doing it this way stresses the fish less than bombarding him with stong current during daylight hours.
400gph im 98% sure.....grab a bottom filter attachment for it too its an extra 10-15$...re-washable (for a couple times) i put mine in 3 days ago....cleaned tank yesterday bottom filter was right brown, so its doing its job, its sucking up 400gph of crap thru that filter part....good thing buddy noticed it while we were at fish store other wise i wouldnt of got it..Thanks for all the replies...whats the gph rating on the ac801?
