I'm new to pool ownership and I've learned a lot from this board. I finally got a decent water testing kit that includes a CYA test (using advice from the site). I show a CYA level somewhere between 500ppm and 250ppm. I did the test initially and it was nowhere near the register so I mixed half tap water and it still didn't get to the 100 mark so I dilluted to 1/4 and finally got reading between 60 and 80. Is this high of a CYA even possible? Is it safe to swim with that much CYA?
I'm showing FC = 4 (after adding 3gal bleach)
CC = 2
PH = 7
BTW, my pool is crystal clear and gorgous but I'd really like to keep it that way.
Thanks in advance for the advice!!!
