Am setting up my first fuge, and looking into overflows & return pumps. Here is what I can't wrap my brain around: which should be rated at a higher max GPH
It seems to me that if the overflow is higher, it will siphon the water level down and break the siphon. If the return pump is higher, the tank will overflow.
I'm looking to setup a small fuge for my 30 gal
-- sort of a "practice" for the larger system I intend to setup in about a year after I move. So I guess I'm looking to move 300 to 450 gph
? Thanks in advance.
