Considering A Salt Water Pool?

While salt water pools are more expensive to install than freshwater pools, they can be cheaper to own in the long run.

Softer Water

The water in a salt water pool is softer and kinder to your skin. The quantity of salt in the water is only 10 percent of that of sea water, which means you won't get salt crystals forming on your skin as you dry in the sun.

No Added Chlorine

Salt water produces chlorine naturally, a big savings since buying chlorine is the most expensive part of the cost of owning a fresh water pool. The salt water chlorinator detects when chlorine levels are down and sends an electric shock through the pool to stimulate chlorine production. The cell in which this takes place is a weak spot in salt water systems because it seems to need replacing at least every 5 years.

No Algae

Salt water swimming pools seldom have algae problems, which spares you another maintenance expense.

pH Levels

Occasionally the PH level or acidity level in a saltwater pool can fluctuate, requiring the use of a stabilizer. Since the PH level of the pool has a direct effect upon the generation of chlorine, it should be tested regularly.

Salt Staining

Even with the low levels of salt used in a swimming pool water you may still see the occasional salt mark on the pool surround from splashed water. But this is very low level and is easily washed away.

Ladder Anchors

Salt water, even in a low concentration, will rust away any steel fittings in the pool. Ladder anchors are typically made of steel or cast aluminum so there is a danger that these will rust through.

Soft Coping

If your pool has a soft coping like limestone, there is a danger that the salt in the pool will attack it. Sealing the coping will solve this problem.

In reality the differences between salt water swimming pools and fresh water swimming pools tend to cancel each other out if treated as advantages and disadvantages. Advances in the care of swimming pools are being made all the time, but at the moment salt water pools win out based on reduced operating costs.
