Ok gonna ask because i really am stumped on this. Looking at building a sump for the Biocube 14. Can i drill 1" hole in chamber 1 for the overflow to the sump and plumb the return line back to chamber 3 that already has the intank return? I know i will need a return from the sump to tank but can control the flow with a ball valve.
