Closing chemistry recommendation

[JimK]

I have never used it. This was my first year even having CYA and I used dichlor. It was very easy. Straight CYA just sounds like a pain... Squeezing a dangling sock, waiting around a week to verify results. Hmmm.

I don't use the sock method. Also doesn't take a week to verify results. At least that's been my experience with my pool.
