I thought I was getting a handle on some of this but then in reading over various topics, now I have this question:
Is there a difference between calcium hypo and regular bleach? I thought it was the same but evidently it is not. I have an AG pool w/ a vinyl liner, can using the cal hypo hurt my pool?
( I think I bought cal hypo as shock last year (bag of powder) in trying to get away from the trichlor and was ok.. but maybe I am not ok.)
