look here...all you need is a 256gph fountain style submersible powerhead, and it will supply several drip sites, adequately...I use 110gph little giants for up to 4 drippers and 256 gph for manifolds bigger than that.
I also, run 2 big plants on one 110gph powerhead with 2 drippers and a 10 gallon rez...then I just drain back down to rez and pump it back to drippers...around and around...I always put a 12-14" bubble stone in each rez, or 2 .88 bubble stones on a T...the more oxygenation, the better.

wally's hopot, tru-Value...all carry submersible powerheads and irrigation supplies to adapt to your pvc. peace
