    I assume that your Cl levels are still very high. The pH indicator will give false readings with high Cl levels. It actually converts to a different indicator that tests a much lower pH range and the color that you are seeing just means that the pH is somewhere above 6.8. You need to let the Cl levels drop to below about 10 ppm and then retest your pH.
