What Is a Saltwater Pool System and How Does It Work?
Saltwater pool systems are among the best alternatives to regular chlorinated pools, which have a harsh smell and sting the eyes. Saltwater pools were previously reserved for spas and resorts but have since become widespread in homes across the US.
This article will explain what saltwater pool systems are, how they work, and their benefits over traditional chlorine pools.
What are saltwater pools?
A saltwater pool doesn't have the same salt levels as seawater. While the ocean has about a salt concentration of 35 thousand ppm (parts per million), saltwater pools generally have between 3000-5000 ppm. The water doesn't taste as salty, is silky on the skin, resembles natural water used for bathing, and doesn't irritate the eyes.
How does this pool work?
Saltwater pools use an electrolytic chlorine generator. The generator separates salt into its components, sodium and chlorine gas. Chlorine gas reacts with water to make hypochlorous acid, the active substance that kills algae, bacteria, and germs in the water. Water testers check the levels of hydrochloric acid in the water. The sodium produced by the generator reacts to produce sodium hydroxide, which increases the water's pH level and stops it from being too acidic.
The generator can use non-iodized, pool-safe, high-quality salt. Use salt that is at least 99% pure. Impurities in the salt will reduce the overall water quality and damage the generator over time. Additionally, don't use calcium salt, as calcium will leave deposits if its concentration becomes too high.
What are the benefits of a saltwater pool?
These pools have a few benefits over traditional chlorinated pools:
Less odor: The chlorine produced by the generator doesn't irritate eyes or have the nasty smell associated with public pools.
Silky water: The saltwater is smoother on the skin and doesn't discolor the hair like traditional pools.
Less testing: The chlorine generator maintains adequate hypochlorous acid concentrations in the water, reducing the need for frequent water tests.
Requires less material: Pure salt weighs less than chlorine tablets or solutions and can be transported more quickly and safely.
Cheaper maintenance: Salt is less expensive than chlorine products, and a generator requires less salt after the initial dumping to achieve the necessary levels. Overall, expect the yearly salt costs to be about 25% of what chlorine would cost for a same-sized pool.
What are the disadvantages of saltwater pools?
Unfortunately, saltwater pools don't come without disadvantages. The generator's price ranges between $1,000 and $2,000 to purchase and needs to be installed by professional technicians. Generator cells can last between three and seven years, depending on how often the pool is used. They cost about $500 to replace.
Additionally, salt corrodes the pool's surroundings. Metal railings, lights, screws, and attachments will rust over time when exposed to the saltier water. Salt can also stain pool decks that aren't professionally sealed and protected.
