Looks like a decent sump for the price, minus the bioballs of course. I don't like the lack of baffles between the return chamber and the skimmer chamber...I guess they are using the bioballs and floss as a bubble trap. I don't like filter socks either, and to double up by adding floss as well. I guess it depends what you're aiming for. Personally, I like this sump for a FOWLR over a reef.
