Improper salt levels
In addition to cell run time, size, and scaling, there are other parameters that can affect the production of chlorine in a saltwater pool. Improper salt levels can cause damage to the cell, as well as inhibit the production of chlorine. Many pool owners often make the mistake of thinking that when chlorine levels are low, simply adding more salt will fix the issue. This may not always hold true. Many pools with the correct salt level may experience low chlorine residuals due to other reasons.
Life condition of the cell
Finally, the cell’s age can also impact chlorine residuals. The electrolytic plates in the cell are coated with a metal called ruthenium. This chemical element is necessary for electrolysis and generating chlorine. As the metal coating wears away with time, the cell’s ability to generate chlorine also decreases. Often, lack of chlorine is due to an aged cell that should be replaced.
Algae growth
One of the most common issues seen in saltwater pools—similar to traditional chlorine pools—is algae. Maintaining a proper free chlorine residual and pH balance is key because many saltwater pool owners choose not to add a preventative algaecide as part of their routine maintenance plan. High pH reduces the effectiveness of chlorine and provides a carbon dioxide rich environment, which can lead to the increased probability of algae growth.
In addition, all of the previous causes of low chlorine residual can contribute to a higher chance of getting an algae bloom in a saltwater pool. Most algaecides are compatible with saltwater pools and should be incorporated into maintenance routines or when troubleshooting algae problems.
Conclusion
Saltwater pools provide a premium experience to pool owners. However, a proper maintenance routine must be followed to prevent problems—the same issues often found in traditional chlorine pools that are resolved by similar activities. That said, some of the problems are exclusive to saltwater pools and require specific products or actions to fix them. The ultimate goal is to provide all pool owners with clear, pristine water, and saltwater pools are no different.
