filter sock?

[FishyFishy!]

In my old sump it had spots for 2 4" filter socks. They worked awesome, however cleaning them constantly sucked. They would plug up and overflow once every 3-4 days. I was going through a tonne of socks. It got too annoying cleaning my sets all the time.

So, I put a sheet of egg crate over the filter sock holders and clamped in filter floss. Worked about the same for catching stuff, only it lasted longer, and replacement was a breeze. I just cut a whole bunch of pads the same size and simply replaced it with a new one when required.

I also ran a larger mechanical filter inbetween baffles in my sump for larger stuff. It barely ever had to be changed. It was black very coarse stuff made for filtering ponds. Worked well too.
