I went to St. louis for a few days and came home to a green pool.
I have shocked and shocked. The pool is not green anymore but my Chloring levels just won't stay up. My CYA level is almost non existant and I'm putting in three gallons of 6.6% bleach a day to keep the shock level up. For a 13,500 gal 24' round pool, thats a lot.
Where the heck is my chlorine going ?
