Running a 55g tank with an eheim 2217 (great filter, low gph
rate) My tank has roughly 60" of head pressure.
Should I buy the Rena xp3 at 350gph max (max 63" head)
Should I buy an aquaclear 110 HOB
at 500gph (no head pressure)
My thought process is, the head pressure is going to drop the xp3 GPH
a ton... So, in turn, I'll get better filtration out of the aquaclear HoB
rather a canister!?!?
