We just installed an Intex agp 32x16 with 17,000 gallons with a SW filter.
I ordered a k-2006 kit earlier and after adding the salt, letting the filter run for 24 hours, I've attempting shocking the water yesterday:

This morning the #s are:
PH: 8
(It took 3 drops of R-0004 to lower sample to 7.4)
FC: 6
CC:0
CYA: 0
TA: 140 (yesterday it was 120, but maybe human error?)
CH: 120 (same as yesterday before adding bleach)

What should I use to lower the PH and what is the best way to add the CYA and what level should I aim to get? I'd love your advice so I don't mess this up!

I've been reading the forum since before getting the pool and it's been an amazing help already - so thank you ALL for sharing your knowledge - I couldn't have gotten the pool and pump set up without all your posts. You are all an amazing resource - esp since the young girls who work at our pool store have no idea!!
