The your bio media getting dirty is the problem... I think more thorough mechanical filtration before the bio media is the solution...
and I don't think it will matter what bio media you use... If the dirtiness bypasses your bio media it goes back into the tank, which is yet another place you don't want it...
In my opinion as opposed to using Bio Media in the sump, more of us should consider using hardy plants. As bio media only address ammonia/nitrite and leaves us with elevated nitrates... Plants / a refugium actually takes that third step that everyone talks abotu wanting their filtration to take...
*Please note this is a completely different "argument" than not needing Bio Media... lol
