Ok- per the awesome instructions here I bought a new Taylor K-2006 test kit... felt like I was in chemistry class again when I opened it I am looking for some help in what to do with these results. I have a Intex AG 16' saltwater pool...
I tested Calcium Hardness first... seemed easiest. The sample never turned red but a light purple. Added 8 drops until it turned blue. According to chart that means a reading of 80. (right?)
PH - was a very transparant orange THROUGH the plastic, with the cover off, it looked like 7.2. Added one drop of PH increase base demand chem for fun and it looked like 7.4.
Alkalinity: five drops using 10 ml sample = 125 (I think that's normal range... dip strips said it was HIGH?!!!)
CyA: The mixture NEVER turned cloudy... the black dot NEVER disappeared. Filled it up to over the 9ml line and still saw black dot clearly. What does THAT mean? Guessing that means non-measurable CA present?
Now for the kicker... Free Chlorine:
I knew I needed FC but this was a shocker! Added the 0870 powder and nothing... 2 more scoops... clear... 2 more scoops clear...2 more scoops clear... I kept adding powder until the water changed to a very faint hint of light pink. I didn't want to waste the whole jug so I quit. Added One drop of the 0871 and it was instantly clear.
What should me next step be to get some chlorine in the pool?
Thanks for your help!
