Just put up the pool, fresh will with well water. I only have the HTH test kit, pH is 7.8 and CL is 3.0 as of a couple of hours ago. I know from previous pools we have metal in the water, last year a fresh fill was tinged green after initial shock, used metal out, a bit of DE through the skimmer and within a few days crystal clear. Yesterday, water was slighty milky, ran filter 24 hours since yesterday morning, added metal out. This morning the water is clear but tinged purple....help??
