I'll keep this brief.

1. Last weekend I vacuumed the brown winter algae to waste and topped off the pool. Water clarity was decent. I could clearly see the bottom liner. Started the filter. See Photo 1.
2. This weekend (Fri) I lowered pH to 6.8 for a treatment of Robelle Metal Out using muriatic acid.
3. Sat morning I added 6 cups of Dichlor. By noon my readings were pH-6.8, TA-90, FC-12.5, CYA-80.
4. Water clarity deteriorated and is now aquamarine/milky, vis = 16 inches. See Photo 2. All brown algae seems to be gone.
5. Filter running 24/7. Visibility not improving.

Is someone tells me how to post photos, I have some to show.
