All I have to say is after using a filter sock, there's no way I'd go ay other way... knowing the crap that I trap every week could still be floating around.... yuck. As for the UG.. yes, amke sure you have LR otherwise you'll shock the bio filter.

I hear ya. But isn't a lot of that gunk actually stuff the filter feeders and such eat? Like plankton etc??

I have a 100 micron filter.... and plankton (phyto)is much smaller than that... so no.. plus, when I feed, I shut off my returna dn let my closed loops circulate for an hour... plus the organics can build, increasing nitrated, OR allowing alage to blossom.
