In lower amounts it does allow a faster depletion of chlorine by UV light but also allows for chlorine to do its work better in the pool. Think of it this way … CYA is sun block for your chlorine. You wear sun block to keep from getting burnt but you do want a tan so if you use too much sun block you won’t get your tan. We want CYA to protect the chlorine from the sun but we still want exposure to the water. If we raise the CYA level we have to raise the amount of chlorine to make up the bonding of the CYA to chlorine. I hope I didn’t confuse you more with this.
As for posting pool info I would put the pool basic info in your sig line and if asking a question for a problem I would post your pool chemistry. It helps the pros here get a better ideal of what is going on.

wow, if you're not a teacher by trade, maybe you should be. I found that to be easily understandable & extremely helpful, thanks.
