    Adding CYA

    Hello TFP. Opened using BBB this year. I began shocking Friday 4/20. I'm now adding 6 pounds of CYA to go from 0-20ish. I started yesterday filling socks and putting them in front of the 3 returns. Very little has been distributed when I periodically check the socks. Seems it will take a week or so to add the 6 pounds. I have been sprinkling a very little around the pool as well.

    Should I add it more rapidly or am I on the right track? I think I read the numerous posts about adding CYA. Thank you.

    You can massage the socks whenever you walk by to help it dissolve faster. I usually can't leave them alone and it'll wind up dissolving in about two days.

    Re: Adding CYA

    Last year I added my CYA directly into the skimmer basket/return. I poured 1/4 of the total amount into both skimmer baskets (for 1/2 the total amount), and then a week or two later I added the 2nd half of the dosage (1/4 per basket).

    It worked well as far as I can tell.

    You do not want any chemical sitting on your liner. Best to vac it up and let the filter catch it.

    Re: Adding CYA

    The massaging is working well. I don't see any sitting on the liner so I assume it disolved. Its still pretty cloudy though. I brush it every now and then to stir it up. Thanks for the advise!
