Yes I can scrape it off with my fingers. I have a Primera stone finish (polished pebble). Its still a chlorinated pool for now since I'm 3 1/2 weeks into filling the pool.Loco, nothing in your water test results indicates a condition which would indicate scale. Have you been able to scrape any of it off and test it by pouring a small amount of muriatic acid on it (fizzle)? I can't tell from the photo and your signature doesn't specify .... what type of pool surface do you have?
It does bubble.... on the TF -100 it says that if calcium is high that it will come out from walls..... but my levels are normal if anything at the beginning of the fill up it was low....for whatever reason I notice that most of the "calcium leaks" are in the deep sideJust to see if it bubbles or fizzles to confirm calcium. So the pool is under a month old then. Still doing lots of brushing I imagine, or not so much anymore?
