fuge crud

LOL. Looks just like the crud in my fuge. Leave it alone unless it really bothers you. If it does, syphon some of it out - but it will eventually just come back again. What I do is I put a little filter floss in the area where my fuge flows into my return section of the sump. That floss will catch any debris/crap before it can get from the fuge to my return pump. I don't want it going into my DT.
