I used southdown for the DSB. This morning the tank has not settled. It's cloudy as heck. I noticed that the sand is very thin, but I would have thought that it would have settled by now. Has anyone encountered this?
I just setup a 20L today with Southdown too. I decided to setup my Magnum 350 with a fresh paper filter to get rid of some of it. It has made a big difference in the few hours it has been on. I doubt it will eliminate the finner particles though.
