yesterday, I dumped 6 Gallons of Bleach, tested Chlorine last night and this morning, did not lose much chlorine. While i vacuumed the white Cristal chunks floated to the top, WHAT IS THAT? I heard it's water mold, if so how to clear it up? i got picture but don't know how to upload to the forum .ps: water still cloudy, blueish light green.
