Answer:

How are your hardness and TDS (total dissolved solids) levels? If you don't know usually your local pool store can test it for you. When these are high you may get cloudy water often, depending on the level. You might consider a partial drain and refill with fresh water to refresh the water and bring more clarity. This also will help to lower the hardness and TDS. A clarifier can also be helpful. Usually maintaining the pH balance and chlorine levels you are suggesting would prevent the cloudy water.
