Help with appropriate shock for vinyl in-ground

[jeepers]

I'll answer the easy bit, first. Use the Amazon page (linked in my signature) and order the K1515 which adds only the DPD-FAS chlorine test. I think Leslie's kit is a private label K2005, so when you add the K1515, you have a K2006.

Ben -
I'm ready to order my kit but wanted to clarify. If I augment my Leslie's/Taylor kit with the K1515, will be I be able to run CYA? It looked like the K1515 may just be a chlorine test and I don't currenty have a CYA test in my existing kit. Does this change your recommendation any?

Thanks again.
