Hey all, I’m upgrading one of my tanks from a standard 110 to a marineland rr 120 with two corner overflows, drilled for 2 1” bulkheads each. I would like to plumb it bean animal style for absolute reliability since i will only see this tank once a week. It seems the major drawback is that one overflow will carry 99% of the water while the other one sits stagnant. I wouldn’t rely on the backup durso drain to allow proper circulation so one overflow will be used for the return line and the backup emergency drain.
Option A- drill a hole or two low down on the return line so the box fills and overflows back in the display.
Option B- drill several large holes in the overflow essentially “deleting” the overflow while keeping the bulkheads and lines protected.
Option C- a small circulation pump at the bottom of the overflow aimed at the surface to keep it from getting stagnant.
Option D- send the return line over over the top and use the extra hole to “T” a line from each overflow to the gated full siphon drain
Any other suggestions? Do any of these methods stand out as problematic or considerably more reliable/redundant than the rest?
