I need pool help. The water is very cloudy.

This is what the test reads:
total hardness is 200
free chlorine is 0
ph is 8.4
total alkalinity is 240
cyanuric acid is 100

What do this results mean? What do I need to do to keep them at an ideal level?


First, you alkalinity and pH are high. The pH should be between 7.2 and 7.8 and alkalinity should be between 80 and 160 or so (the recommendation varies a little based on pool type). Bring them down together using a dry acid. After the pH and alkalinity in the right range, add chlorine to raise the free chlorine level to at least 1 ppm (ideal between 1 and 3 ppm). By adjusting these parameters, you should be able to clear the water up fairly quickly. Hardness and cyanuric acid are ok.
