Hi, Brian,

Nice work on upgrading your pool. I'm sure it's a huge difference.

1. Download "bleachcalc" from any of mwsmith2's post and put it on your desktop. You'll use it all Summer.

2. In many areas of the country, Walmart sells an HTH 5-way kit that tests for CYA...it's a decent kit. That said, I would put CYA in now. Shoot for 25-30ppm and let your tri-chlor and di-chlor add the rest up to around 40 or so. You don't need to test because you know you have zero. Dosage will be on the side of the container and "bleachcalc" will do the math for you, too.

Happy Swimming!
