my sump on my 75 gallon is 32L x 12w x 20H and i run water level at 8" deep for my skimmer to run correctly, i have a euro reef cs5-3 skimmer overall height is 25". i was told 6-8 inches for skimmer area but have seen some 10" deep. plus with my utube style overflow during a power loss my sump will hold xtra water from display until overflow stops and automatically restart when power comes on.
