i can belive what was in my skimmers collection cup , i installed my skimmer yeasterday and today it had this brown sludge that stunk! i was surprised too see that in there as my water looked crystal clear, for those of you that dont use a skimmer take a look in a collection cup at an lfs and ill bet you will walk out of the store with a skimmer.
