My K-2006C kit showed up from Amazon the next day (even with ground shipping) and I have tested twice so far.

The water is clear blue. My pH was a little high so I added 0.5 G of Muradic acid. Here are my readings from this evening:

Chlorine: .02
pH: 7.8
ALk: 90
Calcium: 170
CYA - 0 or N/A (test never turned cloudy)


Two Questions:

1. My chlorine reading is lower at evening, after the pump and chlorine generator are turned off. Is this because the CG is off? Should I be concerned?
2. For CYA test, water never clouded. How critical is this? What do I do to fix it?

BTW, I have the Aqua Turbo Cell Chlorine Generator. I noticed this was not on my signature line.

Thanks,
