Thanks for the quick replies!

It must have been a long while since I had CYA in an acceptable range. I have a "tube" type auto chlorinator that holds 3" tablets, so I would prefer to use that. I guess I just need to keep an eye on the CYA and see when I need to change out some water.

Also, once I get the CYA where it belongs, does the addition of bleach occur fairly infrequently (i.e. every few days) because the CYA stabilizes it?

As an aside, I work for a water district with a water treatment plant, so probably should bring in a sample for the guys in the lab to go over - once I get it to what I think is dialed in. I'd hate to hear them say "hey look at the boss' pool water!'
