Adding CYA

[utahpool]

What is the proper way to add CYA? I have 4 pounds and my CYA reading is 0. My pool is 17,500 gallons. Also where is the best place to by reagents online? I know this has probably been discussed before but I can't find it. Thanks for your help!

Amato sells the reagents and has been a great place for me...

Here's a link to their site:

For the CYA, put it in a old sock and hang it in front of a return jet and it will slowly dissolve. You can even squeeze on it every once in a while to help it break down. It will take a while to get in the water and show up on a test. I'd add 3/4 of what you think you need and then wait a week or two and test as you can always add more but removing it means a partial drain and refill

Thanks for the advice and the link!

Old sock like a nylon or a regular type sock? I'm learning! lol

I used a old thin white cotton sock, but I'd think nylon would work also...

I just slowly pour it into the skimmer with the pump running and let it collect in the filter where it slowly dissolves. Don't backwash or clean the filter for a week. Been doing it for years with no problems (and this is also what I have heard in manufacturer's product trainings).
