Yeah, I was thinking about that, but due to type of overflow and the height of the baffles, theres really no way to use a filter sock as a catch all, or even catch 'most' , lol.
I do currently have a filter sponge to try and catch some of the larger debri that may enter the sump, but thats not very efficient.
I'll just make sure my next tank gets drilled for overflows, and I'll utilize a much more elaborate sump/refugium system.
