Tropical Storm Cindy, that is. My pool went from beautiful blue to green overnight. Must have gotten 4-5 inches of rain last night, pool was close to overflowing.

I feel your pain, razorhog!!!
Pretty sure "she's" to blame for the black algae in my pool, but I'm close to the Gulf, so there's no telling. Mine's finally clear and pretty, but I'm waiting for my chlorine to come back down to maintenance levels.
Best of luck!

PS: Beautiful pool/yard!

Well I started a SLAM but after several tests, I'm not losing FC and there is no CC. Been cloudy all day. It's starting to look better.
