PolyQuat and Shocking with Chlorine

[chem geek]

I guess you haven't heard anything yet from Buckman Labs. From all you've written it sure sound like Quat may be a waste if you follow the BBB method.

I haven't heard from them yet and just sent a reminder E-mail. I doubt that PolyQuat is a waste at normal chlorine levels. The chlorine may only combine with PolyQuat relatively slowly at normal levels -- perhaps over a weeks time (given that it takes around 1-2 days at high chlorine levels) and the PolyQuat may be quite effective at preventing algae during that time. Also, I don't know yet if the chlorine combining with PolyQuat reduces its effectiveness (i.e. does it form a combination substance that is still useful or does it breakdown PolyQuat rendering it useless). So we'll still need to wait and see what Buckman says.
