Pink Mold In Pool

[ltpowel]

I'm testing pool chlorine with OTO/Phenol testkit. Using 5 drops R-0600 to yellow side and got a reading for Chlorine of 5. The range is 1-3. and for the FC test, 10 ml pool water, 1 scoop DPD power (R-870) add 1 drop at a time of R-0871 until pink color disappears then multiply the numbers of drops by 0.5 and I got 3 ppm. I don't see a date on my reagent maybe they need replacing. Thank you for your help.
