I got a Red Sea Berlin skimmer used from a friend of mine (freebie) that is all kinds of dirty. Just wondering what I can use to clean it that will not harm anything in the tank once it is set up. I've heard soap residue will never go away. Is bleach ok? Also- does anybody know a website that I can get just to waste container on top replaced- it was cracked when I got it. Thanks.
