Crash box with 3 drain bulkheads
Two 7" Filter socks
Bubble Trap with an adjustable middle baffle (6" - 10" water height)
Bubble trap is under-over-under style
Two return bulkheads
Two length-wise braces for holding lids and reducing bowing
I have the space between the baffles set to 2"
The space from the bottom of the sump the to the bottom of any baffle/interior-wall is 2"
The return pump area is 8", but it can actually only fit a 5.5" wide pump into this area
The filter sock holder has ~13" of space between the bottom of the holder and the sump, so fits 12" socks
Filter sock area has a 2" overflow wall for when the socks are clogged
Bottom of drain plate and the filter sock plate is ~5", for cleaning crashbox
All interior walls are 2" below the top of the sump
Skimmer area is around 17" x 20"
Would be for a 180 gallon system
