Sump Questions

[Seriak]

I get a lot of crud building up in my one tank without a filter sock. I siphon it out on occasion. My main tank has the filter sock and I get none of that crap building up in my sump. The sump still looks new. You can add a CUC to your sump, but I would rather not worry about what I am going to be sucking out or damaging whenever I am playing with something in my sump.
