When the water contains pH levels that are higher than 8.0, its likely that theres isnt much hypochlorous acid in the solution, which makes it more difficult for amperometric sensors to identify free chlorine. In this situation, its possible that the accuracy of the measurement would be at risk. The vial of water is then placed into a meter to identify how intense the color change is. These test kits provide a chlorine range of 0-3.5 mg/L. Required fields are marked *. Inorganic chlorine is Calcium Hypochlorite for daily and shock chlorination.

Start your pool with a target TA (Total Alkalinity) of 90 ppm and adjust up or down in 10 ppm increments until pH remains stable depending on whether the pH is drifting up or down and help keep these controls these other pool water conditions. Many algaecides contain quats (quaternary ammonium cations) or polyquats. I read somewhere on this forum that if your chlorine level is high, your pH reading tends to be the same purplish color (appears to be 7.7 to me). It can also damage pool accessories, ladders liners, and anything else that goes into swimming pools. If using a colorimeter, run the test in the shade if possible.
