Saltwater Swimming Pools

Saltwater swimming pools are perhaps the most misunderstood of all concepts in the pool industry. If you’re looking for help evaluating the pros and cons of saltwater swimming pools, we can help with a neutral analysis.

Here at Charleston Pool Experts we take a different approach. We offer a complete line of cutting-edge saltwater swimming pool sanitation equipment, from salt water swimming pool equipment to the latest in ultraviolet pool systems.

Our policy is to educate, and then let our clients decide what is best for their pool.

What’s the Purpose of a Commercial Salt Water Pool

Like other pool sanitation systems, the purpose of a saltwater swimming pool is to reduce the level of microorganisms (usually by 99.9% or more) to safe levels.  Some products have a secondary purpose, which is to oxidize organic contaminants such as body oil, perspiration, or sunscreen.  Oxidation is the “burning up” of these organic contaminants.  Saltwater pools usually only serve the purpose of sanitation, and do not have the ability to oxidize contaminants.

Ultraviolet disinfection systems are the most powerful oxidizers available, according to the Professional Pool Operators of America. UV disinfection systems may be added to saltwater pools to improve water quality and lower chlorine levels.

Sanitization

Hayward saltwater swimming pool generation systems generate their own chlorine from a low concentration of salt dissolved into the pool water to create 100% of the pool’s sanitizing needs. The concentration of salt in the pool water is approximately 1/10 of the level in the ocean. This level of salt is equivalent to 1 teaspoon of salt in a gallon of water.

Types of salt

Electronic chlorine generators use ordinary food grade, solar salt or water softener salt. Regardless of which type of salt you chose ensure that it is at least 99% pure salt (NaCl). Never use rock salt (ice melt) or salts that have more than 1% of “anti-caking agents”, “yellow prussiate of soda”, or “sodium ferrocyanide” added as these compounds may cause staining of the pool. Salt is available from most distributors in 40-80 pound bags.

Amount of salt to add to the pool

Hayward and Goldline Controls-brand electronic chlorine generation systems require salt levels between 2700 and 3400 ppm. This amount of salt is below the level of taste for most people and is the equivalent of 1 teaspoon of salt per gallon. Since all chlorine added to a pool eventually reverts to salt, it is very important to measure the salt level in existing pools before adding any salt.
