I just received my first full featured test kit. It's a Taylor K-2006. Prior to this I was just using the small kits that measured free chlorine, Ph and alkalinity. This is my first time with a broader spectrum of numbers. Here they are, what do I do with this water, in what quantities and order, and in what amounts? It's a 44,000 gallon vinyl liner in ground pool on Long Island, NY. It's heated with a heat pump and water temp at this testing was 79 Degrees F. Thanks!
Ph - 7.0
6 drops of R-006 raised it to 7.5 - 7.6
Total Alkalinity - 50 PPM
Free Chlorine - 2.4 PPM

Combined Chlorine - amount didn't register, sample never turned pink ( I used the same sample as the free chlorine - was that correct, or do I refill the tube again with fresh pool water to retest for combined chlorine?)

CYA - 7.0
Calcium Hardness - 110 PPM
Ph Saturation - 8.15
Ph Saturation Index - -1.35
Anyone have any ideas on what to do here? Is any of this really bad? Why don't I have a Combined Chlorine reading? Lots of info here, but I don't know what to do with it. Thanks.
