my sump has a chamber that the overlfows dump into, its about 6w, 18l, 18h
then there is a baffel that goes under then over then into a 2w 18l 4h drop to eggcrate which i put a big long strip of filter floss on. if it clogs, it just raises about 4 inches and goes over the baffel. i also left about 2 inches at the end of the egg create not covered by filter floss for add saftey.
after the filter floss it drops all the way down to bottom of sump and under another baffel to the skimmer.
what i noticed with the filter sock is that it adds back pressure so my herbie gets annoying because it starts backing up and if there isnt a decent 1inch drop in the overflow then i get oil slicks on the top of tank. which i dont mind because it tells me when the sock needs changing but sometimes i dont want to change it right away and it gets annoying. it looks like I will be able to go about a week with the filter floss before i need to add a new strip in. I can get about 15 strips per $4 filter floss
whereas i gota change a filter sock out every 3 days and its $7 bucks for one but i can wash it in the washer (which i dont like doing)
