I'm hoping that switching to bleach only (I've been using bleach and an auto Trichlor feeder up til now) will eventually lower that CYA level.

Sorry to have to ask for old info--I sure miss all those old threads!

Switching to bleach will help--as long as you keep using the tabs, your CYA is going to continue to climb. However, backwashing and refilling with rain, etc. will eventually lower it. (It's gonna take awhile, though! )
