Low chlorine level in salt water syatem even when is between 2900 - 3200?

1. The saltwater chlorinator is not working properly. Check to make sure that the chlorinator is turned on and that the power supply is working properly. You should also check the chlorinator's settings and make sure that they are correct.

2. The salt cell is dirty or damaged. The salt cell is responsible for converting the salt in your pool water into chlorine. If the salt cell is dirty or damaged, it will not be able to produce enough chlorine. Clean the salt cell according to the manufacturer's instructions and replace it if it is damaged.

3. The pH level of the pool water is too high. The pH level of your pool water should be between 7.2 and 7.8. If the pH level is too high, it can cause the chlorine to become less effective. Lower the pH level of the pool water by adding muriatic acid.

4. The cyanuric acid level of the pool water is too low. Cyanuric acid helps to stabilize the chlorine in your pool water. If the cyanuric acid level is too low, the chlorine will be more likely to evaporate and dissipate. Add cyanuric acid to the pool water according to the manufacturer's instructions.

5. There is a high demand for chlorine in the pool water. If there is a lot of dirt, debris, or algae in the pool water, it will require more chlorine to keep it clean. This can cause the chlorine level to drop even if the salt level is adequate. Clean the pool regularly and remove any dirt or debris that may be causing a high demand for chlorine.

6. Your chlorine demand might simply be higher during this period. There are a number of factors that can temporarily raise your pool's chlorine demand. These include things such as high pool usage (especially at times when sunscreen is needed), and periods of significant dirt or dust in the air (such as high winds).
