The Science Behind Pool Water

Salt Water or Chlorine, which is better?

The Science Of Salt Water Pools

Salt cells convert salt into active chlorine for a lower cost as compared to the traditional form of liquid or solid chlorine. Salt water pools reduce skin and eye irritation and greatly reduce the chlorine smell.

A drop of water from a salt chlorinated pool contains less salt than a human tear. Here is a list of typical salt levels in common:

Ocean Water – 35,000 PPM
Human Tear – 9,000 PPM
Salt Pools – 3,000 PPM

  • Pros: Requires a saltwatergenerator as well as basic equipment like pumps and filters. This equipment is very easy to use.
  • Cons: The saltwatercan corrode regular pool equipment and linings. For existing pools, you will need to upgrade to salt-resistant parts and surfaces.

Additionally, saltwater alone will not kill bacteria. People who use saltwater pools are still producing chlorine through saltwater generators. Saltwater will sanitize your pool, but it does so through electrolysis, which produces bacteria-killing chlorine.

The Science Of Chlorine Pools

A salt water pool isn’t better than a chlorine pool because it IS a chlorine pool. Saltwater pools electrically convert the pool salt into chlorine. It’s the chlorine that keeps the pool water clean just like the chlorine you buy in buckets.

Chlorine contains a chemical composition that helps kill bacteria and algae. Whenever chlorine is combined with water, it breaks down into hypochlorous acid and hypochlorite acid. These chemicals help destroy, or oxidize, bacteria, and other dangerous microorganisms to make water safer for personal use.

Chlorinated pools are much better at clearing up bacteria in the water than salt water pools. Chlorine also cleans pool water much faster than salt. Chlorine pools are extremely easy to maintain.

You may have heard in the recent news that Hurricane Laura in 2020 caused the BioLab factory, where chlorine pool tables are manufactured in the State of Louisiana, to burn down.  Although this may result in slightly increased costs in southern states where pools are utilized year round, it is anticipated other products will meet the demands during a period of temporary shortage, if any.

Alternatives to chlorine include bromine, ionizers, and ozonators, though with each you’ll still need to use some chlorine. A fourth alternative is PHMB (polyaminopropyl biguanide), which doesn’t require the use of any chlorine. All four have drawbacks, including cost. Chlorine is relatively cheap.
