How to Clear a Cloudy Swimming Pool
To clear a cloudy swimming pool, first test the pool water for chlorine, pH, Alkalinity and calcium hardness. If the pH or the calcium hardness is off, this will cause a cloudy swimming pool. Next, add chemicals to the pool to get the pH right and to fix the calcium hardness. If the chemicals are within the correct ranges, try running your pool filter for 24-48 hours.
