CYA still not testing after 8 days

[aylad]

Withh the BBB method, once you get things stabolized, how often and how much bleach are you adding. I know it depends on weather etc. But on a typical day (18000 gal pool)

The real answer is--however much it takes to hold your chlorine in the recommended ranges based on your CYA level--you can see the "best guess" chart in my sig to get an idea of what you're up against. In a pool your size, each 2.5 quart of 6% bleach you add will raise your chlorine by 2 ppm, so you can use that as a guide when figuring bleach.
