I have a 15x 48 Intex vinyl pool that has a filter cartridge. This year when we opened it we run the start up chemicals. Now we are having a problem with white flaky particles and cloudy water. We have took our water to the pool supply store to check it and they say that everything is fine except the pH is low. Which we are raising with the pH up. The other tests are normal. We have shocked the pool multiple times as well as multiple of bleach in it. We still can not seem to get rid of the problem. Also, bleach with different filters do not seem to fix the problem. Once we change each filter, we rinse and wash with bleach. Any help with this would be great as I am a newbie to all this pool stuff.
