How could I improve this sump?

[Uroplatus]

What refugium would you recommend?

The sock should be a filter, like a re-usable baby diaper. When dirty, wash it, when it tears, toss it. Always have a few spares too. Like @monkeyCmonkeyDo said, a down pipe an inch or so below the water will help.

Sponge; looks like a bubble-block sponge between the baffles by return pump. That's what I'd change into an eggcrate media rack.

Heaters.. it depends on when to change them, but I wouldn't trust that one for long use. Growth on it means it's been in there for a bit. Never had luck in the past with plastic style ones on freshwater setups.

Protein skimmer in the section with filter sock.

Yeah, a hang on refugium. If that soda ash bottle is your standard 1 gallon jug (5.8in? square), you have a few options. Fiji's for example is 5in, CPR 4.5in..

What are the dimensions of the sump space in the cabinet?
Dimensions of the sump?
Sump current water height (by the sock)?
