I Have an Aqua medic 2.3 (2000lph) running from my return chamber through a pax bellum and then about 4 and a half feet up into the main display as part of the plumbing I'm setting up for a new system. I did a test run and identified a few leaks (over 10 fittings used to run it) but in the end wasn't getting great flow at 100%. I'd expect a decent loss of flow, but would yall think this is too much strain on the pump and should require a larger one? Naturally, this isn't my main return pump.
