I have a 4# bucket of what Leslie's gave me when I asked for stabilizer (even though it doesn't say it... I think it says conditioner... I am at the office right now... I will look later and report). I will add it tonight.

More to your point. No, it doesn't drop to 0, but I don't check it before I put it in every other night either.

How much bleach do you keep in your stock at home? And how much of the other stuff?
