So about a week ago I noticed these white things. According to a few sources these are calcium deposits. Admittedly I was stupid and didn't put any acid in my pool for like three weeks so the pH was off the scale. Since then I've drained two feet of water and refilled the pool and then emptied 2.5 gallons of acid into the pool and the pH has been at 6.5 for a few days now. I go to scrub the calcium with a pumice stone (concrete pool) and I still cannot get the deposits off the pool. I can seem to get the majority of the hard stuff off, but there is still a white streak.
Any clues as to how to resolve this? Thanks in advance!
