This is year 3 for BBB . seems to work.
This year I filled the above ground pool 18' . I put the usual borax & such in it The clorox makes the well water turn cloudy it always does. BUT this year the bottom of the pool is really slippery! Two days passed, The water is clear as a bell now . But the bottm is slick & there is something that looks like sand on the edges only & it is so fine it can only be siphoned out . wonder what that is? & why slippery? that is a new one
