Thanks....I was just reading some of your posts on trichlor and CYA (and I just bought a bucket of trichlor, doh!). Since I have the bucket of trichlor already, could I use use it profusely until it's gone, and then switch to liquid chlorine? Any harm in high CYA levels, other than eating chlorine? I'd hate to throw away 60+ pounds of trichlor. But good advice on the liquid chlorine. I assume it's not stabilized though, so wouldn't I have to add CYA at some point to prevent the UV from burning off the chlorine? Or is there a preferable stabilizer to add?

Maybe a stupid question, but do SWGs generate CYA?
