This tank overflow box too clamp. So cannot run a skimmer in the overflow area.
Result in very erratic PO4 and NO3 the last time.
If I will to reuse this tank might need to do some modification.
Maybe I get an overflow box and a small sump for better water cycling and more
stable nutrient control......

Now looking to convert this AIO with overflow and add a sump below
This display is 30 inch x 24 inch x 18 inch
How big a sump I need?
Is 1 inch overflow enough?
I think 1 inch pvc tubes should be enough id go for as big of a sump your stand can handle fitting under your tank. Make sure to take into account sizing for a skimmer/refugium if you plan on using them.
