I just had my opened last week and there are white crystals growing on every surface that was under water during the winter. The sides, the walls, Â and even the thermometer are coated with hard white crystals. The only surface that is still smooth is the step that was left out of the water when the pool was drained for the winter.Â
Here is some more info: Â it's a gunnite surface and a salt water pool. It was installed in the fall of 2010. We brushed it for 6 weeks or so then it was closed. We continued brushing it when it was opened in the spring of 2011 and for all of last year all surfaces were super smooth. We had it closed last fall by the pool company and opened by them as well.Â
The crystals don't come off when I brush them but I was able to scrape some off with my finger nails.Â
Here are the numbers:
FC - 0 (zero!) (I just turned the SWG on today)
CC - 0 (zero)
Ph - 8.2 (I fought to keep it down all last year)
TA - 120
CH - 600-700! (the test sample never really turned a blue color. It was very faint)
CYA - 55
Salinity 2.4
Does anyone have any idea what caused this and how to get rid of them?
I haven't called the pool company yet because I just got back into town and discovered this last night.Â
Thanks!
Bart
