where's my CYA going

If your pool has a hydrostatic relef valve (which I believe is code throughout Florida) it could have opened and let ground water into the pool since our ground was VERY wet as the storm went through. It's still be raining too hard by me to even check my pool right now and we are supposed to have more rain through the week (NE FL coast for me on the barrier island between the Altantic and Intercoastal and in between Jax beach and St. Augustine beach).

Evan, I'm just down the road from you on Anastasia island off 11th st. I've spoken to you when you used to be at Ace. Our ground isn't super wet because we are built into dunes. The pools isn't over flowed, It's about 2" from the lowest decking area. Water is nice and clear since the liquid cl last night was added. Where would a hydrostatic relief valve be, below the main drain? Our pool is about 12 years old I believe if that give you a hint on the valve. Guess I'll just have to pump more CYA in it after the rain is over and see what happens. I'm just puzzled since it seemed to start while I had the high shock levels going on. At least it seems that the mustard algae is gone, or perhaps just hiding.
