Yes, I mentioned this yesterday. I already added my floater back into the pool a couple days ago (Tri-Chlor 1" tabs). I use granular Di-Chlor as my regular sanitizer. You suggested I wait until my FC comes down to 3 or 4 before adding any. I shocked last week using liquid chlorine (Walmart had a sale for boxes of two, 1-gallon jugs of HTH liquid chlorine for $6.50!) but I don't buy liquid chlorine typically.

You suggested that people don't stay on top of their chlorine 100% the time, and that is almost certainly true of me, but I'm pretty sure I'm more diligent than the average bear. I believe I'm learning that my chlorine has been sabotaged by my low (perhaps zero) CYA levels. If none of what I just said is true, then I'm really wasting time, and have done too much online reading.

Thanks for listening and sharing.
