Pool Stains - unsure what kind and best way to proceed

[tmcdonald]

Here's my test info....as best as I could get

free chlorine: 2 drops x .5ppm = 1ppm by my calculations
combined chlorine: 1 drop x .5ppm = .5ppm
ph: 7.0 or below...close to 7 though by color
alk = 6 drops gave me a pink color..not red...11 drops in I was still pink so i stopped. that would give me 60ppm-110ppm...but again..never turned red.
calcium hardness: water turned pink/purple around 10 drops in...it was lighter purpler at 30 drops in..never turned blue and I stopped at 30 drops.
cyA: I got half way between the bottom and the first mark at 100 - no number was present.

Sorry things came out kind of funny..let me know if I need to adjust or if that gives you a good enough idea what I'm dealing with
