I've been working on getting my in-laws small Walmart pool clean and safe and eventually gave up and had to drain it. It was full of a very fine white silt that I was unable to get rid of. I even got rid of the cheap filter and stuck a 19" sand filter on the thing, stuff went right through it. Water looked like milk as soon as you got it stirred up. Anyway we drained it and cleaned it out and I'm getting ready to start getting the water stable, problem is the TA is 310 out of the tap. PH is a just over 8 so I put a half jug of muratic acid in to try and get the TA and more importantly the PH down. Question is, since this is not a plaster pool; what will be the negative effects of have TA 200+? I know I need to monitor the PH really well but is this something I need to really worry about health wise? Can't be too dangerous since it city water right?
