Answer:

Pool water that is cloudy and irritating indicates that the water is not properly balanced. It may or may not be safe to swim there. It could be as simple as an unbalanced pH, which would potentially cause both of the problems you are reporting. However, it could also indicate a lack of free chlorine or too much combined chlorine. Either scenario would present a bigger problem and could mean the water is unsafe to swim. You should at least test the pH and free chlorine levels to make sure you are not exposing yourself to potential illness.
