Softswim to Chlorine this Spring

[tcjones]

I am looking at a very clear, but lemon/lime-colored pool and need to a boost to morale. I have added 18 gallons of bleach so far...

I am using the DPD #1 and #3 tablets (0.0 to 5.0 ppm) to test for CL and I am having difficulty getting a test result when I test in the morning. Is there a problem using the DPD tablets during the conversion? I have even tried a 2:1 and 4:1 dilution and the results are not what I would expect.

I did add dry acid (low 's slo from last year) to drop the pH about 0.4 units. I'll test the CL again after a few hours.
