I have a 75 gallon reef with 20 gallon sump and 10 gallon refugium running off sump. My tank does not have a built in overflow so I have a 1 1/2 inch bulkhead drilled into the right corner to drain the water into my sump. The return is a mag 12 split into two return lines, each of which hang on the back of the tank and end in a "Y" and loc-line (the black plastic stuff you can bend in any direction).
I will be drilling a second bulkhead to drain to the sump this weekend for added insurance in case the first gets clogged. My questions is this - While I have some of the water drained, is there any benefit for drilling two additional holes for the return lines from the sump? (they currently hang on the back with 2 ninety degree pvc elbows.). It seems to me that the lines would be more stable (right now they slide). In addition it would slightly reduce the pump head pressure, as I would get rid of the two 90 degree turns required to get over the top of the tank. Any thoughts would be appreciated.
