Since I've opened my pool a month ago and evicting two frogs out, I've been dealing with white mold. I have a 3500 gallon 14'×32" bestway pool. I have two catridge filters running 24/7. I have tried shocking the pool, sweeping the bottom, brushing the sides, and cleaning the filters twice a day with no luck. The pool company I test my water at has no idea how to fix my issue other than maintaining chemicals, and shocking the pool. My problem is after shocking at night the next day the sludge is at the bottom, but when I sweep it the catridge only collects so much of the sludge, and sends some back into the pool. How do I get rid of this mold? Any help is greatly appreciated.
