I just noticed yesturday that I have a lot of tiny white spots stuck to my glass and the airline going to my skimmer. I have done a search and I have narrowed it down to some things that it is not: It is very tiny white things that looks like a piece of lint. It is not in a spiral shape but more or a straight line. It does not appear to move and I even looked at night and it is not moveing. I can run the magnite over them and they will rub right off very easy. All test seem to be fine except nitrate but it is only 20. Any have any idea what this could be?
