Disadvantages of a Salt Water Swimming Pool

Initial Purchase Costs

Automatic Salt Chlorinators can cost in the range of $1,000 to $2,000. If having a salt chlorine generator does save money, which is disputable, the return on investment can take many years to realize.

Chlorinator Repair Costs

How long will the salt water chlorinator last? Older models have been known to break down within 3 – 5 years. Although the newer models are beginning to show better longevity, there is still a good chance that the chlorinator will need some type of repair within 5 years. This needs to be taken into consideration when considering buying a Salt Water Chlorine Generator.

Increased Chemical Costs

Although there is a major reduction in the cost of chlorine for a salt water swimming pool, the pool water still needs to be tested on a routine basis, plus there are increased costs for other chemicals with a salt pool. First, the salt level needs to be maintained which involves monitoring the salt level and periodically adding salt to the pool. Secondly, salt pools tend to operate at a higher pH level requiring for muriatic acid than needed with pools using conventional chlorine. Lastly, although a minimal cost, the stabilizer level needs to be tested a couple times per year and cyanuric acid will need to be added in order to keep the levels at a minimum level of 20 ppm.

Out of sight – Out of mind

One of the biggest issues that owners of swimming pools with salt chlorine generators face is that the salt swimming pool systems are sold as "maintenance free". This leads pool owners to think the only task they need to pay attention to is the level of salt in the pool. Unfortunately, this couldn't be further from the truth. The pool water chemistry still needs to be tested weekly in order to keep the pH, alkalinity, stabilizer level, and salt levels in check. Without routine maintenance, there are many issues that can lead to big problems with the pool water very quickly.
