I have built a 315l DT with a 75l sump. Drilled with 1"1/2 overflow and 1" return.
I'm using a 3500lph pump that can be adjusted for flow. The problem I'm having is not being able to get water back into the sum quick enough. Is my pump to powerful? I was planing on using the snorkel method ( h shape )to silence the overflow and hoping that would draw more water into the overflow stand pipe. Any Ideas guys?
Also I bought this sump brand new but never used (picture below) it came with bio balls but had been told they can be a nitrate factory so was going to remove them and replace with live rock, I don't think a sand bed would work on this design unless I install another baffle. Also I would prefer not to use algaes as filtration as I don't want to use a light. Thank for any advice
