Trouble reading PH

[joel98z]

To me this does not match any colors.. I assume this may be 8 or over? How should I interpret this reading?

What is your FC using the FAS-DPD test?

Assuming that is using the R0870 and R0871? If so FC was 3

Great. Just checking as FC above 10 ppm effect the pH test.

Assume the pH is 8.2. Use Poolmath ( you will need a current TA test result) and add acid to lower the pH to 7.4. Add the acid, circulate/brush the pool, test the pH 30 minutes later. If still not in the 7's, repeat adding acid, etc.
