I'm hoping to just do the B method this year.
I did go out and get stabilizer before opening, then tested and found I was still in the perfect range.
So, when I opened, I dumped in a couple of gallons of walmart brand Chlorine and that was it, so far, that's all I've added, everything else is staying perfect, seems like it might just be a "bleach only" year!
AND, it's been nothing but HOT HOT HOT up here - my kid's loving it and so are we!
