your also going to want the aqualifter ( the pump thats on top there ) to prevent having unwated siphon breaks which would be disasterous.
Can you use a durso with an overflow box? I ask because of the small hole drilled in the top of the durso pipe, designed to keep a small pocket of air at the top of the pipe.
