Adding CYA

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).

Thanks for the advice!

I use the skimmer method, too. I get most of my reagents from http://www.spspools-spas.com. Shipping is quick, prices are good, and they've always been very courteous and helpful-- but then again I call them and tell them what I want, I don't ask them for advice...

Janet, about SPS, I'm putting together a refill list and thought I'd give them a try but I don't see where they have the Taylor R-0014 pH reagent. Am I just not finding it? Do you get that from them?

No, I think I got the last one at TaylorTechnologies.com. I have also bought it in the store at Leslie's, when I'm in a pinch
