Had the worst hailstorm in Okalhoma City's recent history yesterday and my pool got vey cloudy immediately. Lots of shredded foliage in the pool - is that the reason? FC is 5, Ph is 7.5. Anything else I should check? I've never had a problem with inches of rain but maybe the hail is different? It has cleared some overnight but not completely! Patio chair in 5' water

Lots of organic debris will do it. You should raise your FC level up to the high end of the normal range for your CYA level, scoop out everything you can, and give the filter some time to catch up.
