Ok i am going to be running a 180g soon, i will be pushing anywhere from 800gph-1000gph. My question is, will a single 7"x16" 100micron sock? and actually last a couple days before it overflows? I know this depends on how dirty the tank is, but its just going to be geos and severums. It will be fed with 2 1" piping. Any help would be great.
