Seems like I forgot it all during the winter

I assume CA = CYA?

If so, I'd drain and refill first and THEN add CYA. Doing the other way round will waste a lot of cyanuric acid.

maybe I am reading this wrong.. but are you saying to drain the pool.. if the CYA reading is 5? I don't understand. Seems like a drastic move. but I am just a pool dummy.. so go figure.

by the way PoolDoc... good to see you back regularly. this site was BIG HELP about 6 years ago when we first installed the pool.. and I always come back.. and always tell people about the site when they ask me why I am buying 20 jugs of bleach and a six pack of "Blue Moon" every spring.

Chuck,
Ben was suggested that if this poster needed to drain some due to salt levels being too high, that he do so first before adding the cya. Otherwise he is wasting the cya and his money.
