I will start with the conditions from last year. Water stayed milky white settling on the bottom. This year started out with bleach to reopen pool. pool turned clear yet still had the residue. I made a gravity vacuum to get it out, water was clear enough to see the bottom . I then filled up the pool with another foot of water. Added stabilizer Water turned green I added a half gal of bleach. I can test the PH it is now 7.2and now chorine if off the scale but dropping. I vacuum residue daily till it gets to cloudy to see what I am doing. Our water is from a well if that helps at all. I know a better test kit is needed and when I can get to town I will but that could be a while
