Chlorine confusion

[GregP]

Thanks for the information. I still don't have the pool opened up yet. In PA lately one day it is 80 degrees and the next there is a hard frost. I want to get it up and running hopefully in the next couple of weeks. My pool store carries the liquid chlorine, but I do not know the strength or price. I gave up on the pucks and chlorinator, it is not worth the problems and hassle that I had with it.
In reading PoolDoc's reply, if the Dichlor and Trichlor is "pure", then is it free of CYA?
Thanks

No -- if it was, then it wouldn't be dichlor or trichlor. "Pure", in this context, just means, "not blended with other goop".
