Any time I scrub my pool with a stainless brush, it kicks up clouds in to the water. When I am finished, the entire pool is cloudy. After a few hours the water is crystal clear again. Is this calcium scaling getting scraped off of the walls? Am I damaging the plaster? My CH is somewhere between 400-500, hard to read the color right, I suffer from a fading endpoint. I have slowly brought the TA down over the past few months from close to 200 to 90.
