Hope you don't mind, I merged these threads together because it's much easier to give helpful advice without repeating myself if all the information is in one place.

You want to keep your chlorine level between 12-15 ppm untl it clears. As long as your stabilizer level is 25, don't go above 15 because you risk bleaching your liner. It is not a good idea to just keep dumping bleach in the pool without measuring first--that's a really quick way to bleach the liner. In a pool your size, each gallon of 5.25% bleach you add will raise your ppm by 1, so measure first and then adjust what you add accordingly.

As for the white stuff on the bottom, you can shut your pump off and let it settle to the bottom, then vaccum to waste, if that appears to clear it quicker. If not, then keep stirring it up and leave your pump on, so your filter can get it.

The reason I asked about the Clorox is that Clorox this year started adding a new whitening ingredient of some kind that has a tendency to create a white precipitate. Check specifically the Clorox label--the generic stuff from Sam's isn't a concern. That's why most of us stay with the generic bleach and not Clorox brand.
