Sorry -- I missed answering that. Increasing CYA is easy and you have choices. You can buy pure CYA at your pool store. It takes a while to dissolve and you can put it into your skimmer to have it caught in the filter where it will slowly dissolve. A more expensive alternative is to use Natural Chemistry Instant Pool Water Conditioner, but that will dissolve instantly. If you don't need your CYA raised in a hurry, you can just use Dichlor for your regular chlorination and the CYA will build up rather quickly over time since for every 10 ppm Free Chlorine (FC) added by Dichlor, it will increase by 9 ppm.
