I am in the middle of a Slam. My water was green although I could not see algae growing nor was any picked up with the vacuum. First time doing a FAS-DPD testing. My CYA was high at 65 so I had to slam hard. Please let me know if my calculations are correct. 1. Filled to 25mL. 2. After adding R-0870 the sample did turn a dark pink (have pic if needed). 3. it took 82 drops to go to colorless. 4. 16.40 ppm free chlorine. 5. Turn a light pink. 6. R-0871 added 4 drops then turned pink = 0.80. 7. Multiply dorps in Step by equ. = 0.80?????? Is this correct? The Target FC around 8/10 and Slam should be 28 according to the slam chart. If this is the case I am still way under the slam? My water however is not green anymore. It is a cloudy white color so I know something is working. Help!
