i just started plumbing so my sump needs to be filled with actual filter material next. I used to have the water come in and fall on nylon floor scrubber pads in the end chamber, middle chamber was filled with lava rocks, then pump out after bubble wall. this sump used to be for saltwater and had a bioball wet/dry. I have a huge amount of bioballs but no room for the dry parts of the wet dry. dimensions are 48"x18"x18". the end chamber is 17", middle is 23", then the bubble wall end chamber.

end chamber 17"


middle 23"

bubble wall

starting plumbing the overflow
so i'm thinking about having the water drain into filter socks in the section before bubble wall, then fill the second chamber with some kind of mechanical, maybe poret foam??? then do pot scrubbers in the last section with the pump and heaters? should I add a baffle in the second (middle)chamber ? guess im not sure how to maximize my sump. its on a 240g that's going to house lots of bichirs and a few other large fish.
and I have looked at the lets see inside your sump thread hence the questions. thanks in advance!
