Thanks Watermom!

I just tested FC/CC again. My FC went down to 16 - but my CC is 0. I'll add more CL and get it back up to 20.

My CYA was still right around 30, so I put my CYA sock back in (there's maybe a 1/2 pound left in it). Was that wise? Is 50 the goal I'm reaching for with CYA?

(can kids swim while we're doing this?)
