Howdy Evan!

I've learned here that there is a relationship between CYA and chlorine, but your post is the first I've read of the relationship of CYA and alkalinity readings. My CYA is very high (120 ppm), so I'm interested in this aspect of it.

I've tried the search function without success, so I'm wondering if you could point me to a thread where this is further discussed.
