I have recently been planning a 30 gal sump tank to add an Algae turf scrubber. I want to ask if anyone has any opinions on to help me make this an easy install. My questions I have are there is a 1/2" outlet on my Mag 7 pump I purchased. Should I run a 3/4" PVC piping back to the tank, or should I go up to 1"? The pics are a side view of the tank, cutting threw the wall to and from the sump Should I add Live rock rubble to minize splashing? Also I was thinking to use braided tubing off the pumps, but will probably look for some screw to pipe converter to them. Thanks in advance
