Welcome to our forum.
You are a seasoned owner that knows about water care, there is a difference. I too would experiment with any chlorine, I was thinking about doing just that with bleach and maybe cal hypo.What I said before about beating the system I believe especially after being a "only use bleach" pool forum member. The truth is that cal hypo on sale is just as cheap for me as using bleach. People, myself included as a newbie, also don't know squat about the chemicals and their interaction on water care. "chlorine is chlorine" is what most people think. Some choose to become educated in water care and some do not.
