I have a problem with a fine dust that constantly accumulates in my pool after vacuuming. My readings are good, FC 3, CC 0, TA 100, PH 7.5 & CYA 30. I've read the other threads regarding similar issues. My main question is that I do use Pro Teams Metal Magic on a weekly basis because in the past I have had metal issues. Has anyone heard of that product adding to this "dust" problem? Just trying to rule things "out".
