Hi, I've been following the TFP method since I acquired this pool from a home purchase. I bought it about a year ago and had no clue about water testing so I found your site to get me going. I closed the pool a month after I moved in so this was the first full year. Everything has been going great except for the white spots in the deep end. If have tried scrubbing but 2 of them are really thick and like concrete. The other have appeared slowly as the season progressed. I don't add anything to the pool that can settle except salt and borax which I follow with brushing and then put the robot in to mix. I tried scrubbing them but they dont come off. Any ideas?
