Why is my pool water blue and not clear?
Pool water with a high total alkalinity (TA) is often associated with cloudiness. This is because it can cause an imbalance in the pH levels and lead to calcium scaling. Typically if your TA is higher than 200 ppm, you’re at risk of a cloudy pool and just like imbalanced pH levels, your chlorine will be less effective.
