If I drill a hole down low in the first chamber (circle with blue), and put a pump as a secondary return, will this design work?
Trying to rule out possible problems. Something doesn't seem right with the first baffle. Will it be safer if the first baffle has the sane height with the overflow?
Reason I'll want a second return pump is that I dont want circulation pump in the display and second, dont want to place 2 pumps in the last chamber to avoid a tsunami in the refugium.
