Saltwater Pool: Fact and Fiction

There are a number of misconceptions about a saltwater pool and generators (also known as a salt cell or salt chlorinator). So let’s break down the persistent myths of salt systems…
Myth: Salt water pools do not contain chlorine.

Fact: A salt water swimming pool is a chlorine swimming pool. Through the process of electrolysis, the salt molecule (NaCl) in the water is split apart making hypochlorous acid (HClO) and sodium hypochlorite (NaClO), which are the sanitizing agents already commonly used in swimming pools.

Myth: Salt water is safe to use on any inground or above ground pool.

Fact: Salt corrodes metal. Unless your pool is made of a noncorrosive material (such as a resin frame above ground pool like our Mystic II) we recommend to steer clear of a salt water system.

Myth: Salt water generators last a lifetime.

Truth: We recommend replacing your salt water generator system every 3-5 years. We recommend you clean your cell every 6 months and add cell extend every month to get the full 5 years out of your salt water generator.

Myth: You can use any type of Algaecide on your salt water pool.

Fact: Most Algaecide products contain metallic minerals (such as copper) as their active ingredient. Metals can damage salt cell chlorinators, so we recommend using our Poolife Defend+ Algaecide, since copper is not the active ingredient.

Myth: You can add table salt to your pool water.

Fact: There are different grades of salt. Swimming pool salt should be the only type of salt added to your swimming pool.

Myth: You add the pool salt into your salt water generator or skimmer.

Fact: DO NOT DO THIS! Leave your PUMP ON to circulate the water and help dissolve the salt. Add your pool salt directly into your pool water and stir with your telepole and brush.

Myth: Salt water chlorinators are maintenance free.

Fact: In order to extend the life of your salt cell you must maintain proper water chemistry (balance pH, alkalinity, hardness, stabilizer) and clean the cell when deposits occur.

Myth: Salt water pools smell and taste like the ocean.

Fact: If balanced properly salt water pools do not smell or taste salty. The salt level is so low it is can still be classified as fresh water.

Myth: “It costs too much”

Fact: Salt water generators may have a larger up-front cost, but in most cases salt water pool owners spend significantly less on pool chemicals throughout the season.
