Salt water pools are growing in popularity as an alternative to traditional chlorine pools. The benefits of owning a salt water pool are impressive and may have you considering the switch.
Contrary to popular belief, salt water pools are not chlorine or chemical-free, but they are safer because pool owners do not have to handle the chlorine in its physical form nor find a good place to store it. You might be surprised to hear that salt water swimming pools use chlorine to keep the water clear. A salt water pool generates chlorine through a process called electrolysis. Salt is added to the pool, the water passes through the chlorine generator, then converts the salt into chlorine using an electric discharge. Salt water pools use a salt water chlorine generator (SWCG) to turn salt into chlorine. The chlorine eventually breaks down, leaving behind the salt to be reused.
Maintenance & Cost Savings
A SWCG makes it easier to maintain constant, proper chlorine levels. This allows you to avoid high chlorine levels that commonly occur in traditionally chlorinated pools, causing eyes to dry out and become irritated. Salt water pools ultimately save you time and money on costly chemicals, after the initial purchase and installation of a SWCG. Salt pools are also cleaner because the generator runs on a consistent schedule.
Skin Care & Health
A salt water pool leaves skin feeling softer and smoother upon exiting the pool, unlike non-SWCG pool water. The water is soft and won’t leave a noticeable residue in your hair or on your skin. Salt water is also known to exfoliate, rejuvenate and detoxify skin.
As far as health benefits, swimming is great exercise and a proven stress reliever. Salt water pools are even more beneficial because they make swimmers more buoyant and help to relieve inflammation in your joints and muscles. With a salt water pool, there is the added bonus of not exposing yourself or the environment to as many harmful chemicals.
Whether you’re considering an update or planning to build a pool, salt water pools are an excellent choice.
You might be surprised to hear that salt water swimming pools are using chlorine to keep the water clear. Salt water pools use a salt water chlorine generator (SWCG) to turn salt into chlorine. The chlorine eventually breaks down, leaving behind the salt to be used again. SWCGs are not a new concept, but they continue to evolve as the technology and materials improve.
Benefits to Salt Pool Water
Many homeowners prefer salt water swimming pools for the following reasons:
A salt water pool leaves skin feeling softer and smoother upon exiting the pool, unlike non-SWCG pool water.
A salt water chlorine generator makes it easier to maintain constant, proper chlorine levels, avoiding high chlorine levels that can commonly occur in traditionally chlorinated pools causing eyes to dry out and become irritated.
Salt water pools reduce the need to frequently and manually add chlorine to your pool.
Salt water pool owners do not have to handle the chlorine in its physical form, nor find a good place to store it.
How Salt Water Chlorine Generators Work
“Salt water chlorinators use dissolved salt as a means of creating chlorine to clean the pool. They use a different process to create the chlorine instead of just dumping the chemical into the pool.
A salt water pools make hypochlorous acid (HClO) by using table salt or sodium chloride (NaCl) and electrolysis. The salt water passes through an electric current creating chlorine gas (Cl2), but you’re also forming hydrogen gas (h2) and sodium hydroxide (NaOH). Using electrolysis, dissolved salt is converted into hypochlorous acid(HClO) and sodium hypochlorite, the sanitizing agents used to clean the water of any dirt and bacteria.
So, instead of just dumping chlorine into the water, you create a chlorine generator with a salt water chlorinator that continues to generate chlorine until more salt is needed.” – Swim University
Adding a Sacrificial Anode
A zinc sacrificial anode is a device that protects metal components from corrosion in a salt water pool. Salt water is corrosive, regardless of whether or not there is chlorine or an active chlorine generator. The large increase of dissolved solids in the water when salt is added makes the water more conductive, and can lead to premature corrosion of any metal components in the pool system. Adding a sacrificial anode made of zinc, a softer metal than all the stainless steel and aluminum in pool environments, and attaching it to the bonding grid, means that it will corrode before any of the more important metal components. An anode’s role is to corrode (sacrificing itself) before other metals that are part of the same underwater electrical system. Talk tous today about scheduling installation of a sacrificial anode anti-electrolosys device to your salt water pool. We highly recommend it!
SWCG systems make pool maintenance easier for salt water pool owners. A well maintained salt water chlorinator system should last you anywhere from 5 to 7 years, when serviced periodically. Spend less time managing chemicals and more time enjoying your pool!
