Filled pool last year after refinishing to pebble and got CYA to around 50 (overshot some, really wanted 40).
This spring I notice the pool is consuming chlorine a lot faster than I expect. Test the water and there's basically no CYA at all. Local pool store confirmed the numbers. I don't use pucks.
By all accounts I've read, only way to rid myself of CYA would be to drain water and that hasn't happened. Virtually no rain over the winter.
Where'd it all go?
