  • Low chlorine levels: Chlorine is essential for sanitizing the pool and preventing the growth of bacteria and algae. Maintaining proper chlorine levels is crucial, and if they drop too low, you can add more chlorine using tablets or shock treatments specifically formulated for salt water pools.

2. Low Chlorine Levels And Solutions

Low chlorine levels in salt water pools can be frustrating and contribute to cloudy water. One potential cause of low chlorine levels is clogs in the saltwater chlorinator cell. The chlorinator cell is responsible for generating chlorine from the salt in the water, so any obstruction can hinder the chlorine production.

To resolve this issue, cleaning the chlorinator cell is necessary. You can use over-the-counter cleaner specifically designed for salt water chlorinators or opt for acidic substances like muriatic acid or vinegar. These acidic solutions help to remove any deposits or clogs inside the cell, allowing it to function properly and produce adequate chlorine.

Another common reason for low chlorine levels is not running the salt water generator for enough time or at a sufficient power level. If the generator is not operating at its optimal capacity, it may not produce enough chlorine to keep the water clear.

To address this issue, increase the power level of the salt cell or run the salt cell for a longer duration. This can help increase chlorine production and clear up the water. Always refer to the manufacturer’s instructions for the specific settings and recommendations for your salt water generator.
