Got our new liner installed this week.. Love it! I was a little apprehensive on filling the water from our well, but I am 3/4 of the way there (12 hours at a time) and so far so good. Notice the stained steps.. I figured I had some metal issues, but I had the water tested today at PS and no metals found (TFT kit on the way).. I find that hard to believe there is no metal given the steps and well water.
I was able to clean up the step stains using pressure washer and softscrub. Here are the current numbers:
My first idea was to get more chlorine added and add a bit more CYA.
