hey so i have a sump on my 180 but debris still goes in the tank.. i have a sump with a drip plate and i put that white cheap filter foam/floss stuff that feels like cotton from a lfs and it lets stuff bypass it.... so i was wondering what i can put on my drip plate to make sure no debris by passes it.... can i lay down a bunch of filter socks or do those have to hang ..also i heard about this poret filter http://www.swisstropicals.com/Poret Filter Foam.html and has anybody used that on a drip plate and is it any good thank you
