Thanks for the quick response.

One other question-
Are you aware of anyone making some form of chlorine tab that could be used in a chem feeder and does not contain stabilizer- or at least lower levels of it? Trichlor is ideal because of the convenience, but I'm sure I will eventually reach a point where I am forced to switch to bleach to avoid high cya levels. Seems like that would be a good opportunity for some chemical company to sell more pool products.
