Boosting Salt Cell Efficiency: Guidelines for Long-Term Performance

Saltwater pools have changed the game in pool maintenance by providing a more eco-friendly and convenient option compared to traditional chlorine. The salt cell, at the core of these systems, plays a key role in transforming salt into chlorine using electrolysis. In order to maintain the efficiency and longevity of your salt water chlorinator, it is vital to know the proper procedures for operating the salt cell. This detailed guide will help you optimise salt cell performance and extend its lifespan with best practices.

Understanding Salt Cell Basics

Before diving into maintenance tips, it’s crucial to understand how salt cells work. Salt cells contain metal plates coated with ruthenium or iridium. As saltwater passes through the cell, an electrical current causes electrolysis, converting salt (sodium chloride) into chlorine gas and sodium hydroxide. These components then recombine in the pool water to form hypochlorous acid, the active sanitising agent.

Dos for Optimal Salt Cell Performance

Maintain Proper Salt Levels

Similar to other pool equipment, salt cells need consistent upkeep to maintain their performance and longevity. Regular cleaning of the salt cell is important to prevent a decrease in efficiency caused by calcium buildup. Establish a regular cleaning schedule based on your pool’s usage and water hardness. For most pools, cleaning every 3-6 months is sufficient. Use a mild acid solution or a manufacturer-approved cleaning product to remove scale deposits.

In certain situations, the cell might require replacement. Indications that your salt cell plates require replacement may consist of frequent error notifications on your pool’s control panel, decreased chlorine levels, or slow water flow.

Maintain Proper Water Chemistry

The right water chemistry in your pool not only ensures swimmer comfort but also prolongs salt cell life. Keep pH between 7.2 and 7.6, alkalinity between 80-120 ppm, and calcium hardness between 200-400 ppm. Proper balance reduces scale formation and prevents corrosion.

Pool Cover

A pool cover reduces chlorine demand by preventing UV degradation and debris contamination. This, in turn, reduces the workload on your salt cell, potentially extending its life.

Don’ts That Can Shorten Salt Cell Lifespan

Don’t Turn Off the Pump for an Extended Period

The main function of your pool pump is to circulate water at the required flow rate to activate the salt cell. If the pump is switched off for an extended period, chlorine levels in the pool will decrease considerably, leading to the growth of bacteria and algae. Moreover, standing water inside pipes can result in the growth of algae and other bacteria in your pool.

Avoid Excessive Chlorine Production

Running the salt water chlorinator at maximum output unnecessarily shortens cell life. Adjust chlorine production based on your pool’s needs, considering factors like bather load and weather conditions.

Avoid harmful Cleaning Methods

Never use metal brushes or abrasive materials to clean the salt cell. These can damage the delicate coating on the plates. Stick to manufacturer-approved cleaning methods and products.

Don’t Ignore Warning Signals

Modern salt chlorinators often have diagnostic features that alert you to potential issues. Pay attention to these warnings and address them promptly to prevent damage to the cell or system.

Avoid Draining the Pool Without Precautions

If you need to drain your pool, turn off the salt chlorinator and remove the cell if possible. Running the system without water can damage the cell and other components.

Concluding Thoughts

By following these tips, you can significantly extend the life of your salt cell and ensure optimal performance of your salt chlorination system. Regular maintenance, attentive monitoring, and prompt addressing of issues will not only save you money in the long run but also ensure your pool remains clean, safe, and enjoyable for years to come. Remember, a well-maintained salt cell is the key to effortless pool sanitation and crystal-clear water.
