I got the k-2006 and here are the numbers...

Ph=7.4
FC=15ppm
CC= 1ppm
TA=210
CYA= 30

So if I understand things correctly, I can stop adding chlorine now right? CC is down to a negligible level and FC is up?

What's next? Pool is still pretty cloudy. Not sure how efficient my filter is. I have replaced the sand in it once but's it probably been 4-5 years. I have added DE to the filter as of last night. It didn't go from 18ppm (after DE) to about 24-25 and at that point the flow had been reduced greatly so I backwashed and added DE again tonight.

Anything else I need to do tonight? Chlorine?

Thanks!
