It's me again...The Chlorine is where I am confused. I have read some of the info online, but can't seem to get my levels where I think they need to be, or maybe I'm not sure where they need to be.

FC is 1.5, CC is 2, PH about 7.5, ALK 100, CYA 40

Based on what I am reading it looks like with the CYA of 40 the FC should be between 3 to 5. The CC should be 0. How do I get those numbers there? I didn't want to put too much bleach in the pool. One question I had...I am using the 10ml sample to test. I add 2 dippers of the powder...it is light pink. Then I add the drops counting. Then I add (it says 5) drops of R3...is that for the 10ml and the 25ml sample? or should I add less for the 10ml?

I just want the pool to be sanitized before we swim...which will be a little while. It is still pretty cold. The water looks great though I do have a little staining around the main drain and around the water level at the steps. Not sure where that came from. I'll take some vitamin c to it soon.

Thanks for any suggestions.
