A salt water swimming pool is more expensive to install compared to a regular chlorine pool. However, after the installation, you do not have to spend on buckets of chlorine. This means that you can save money in the long run on the buckets of chlorine. You will still need to balance the pool water, with adding balancing chemicals. When the generator is making chlorine, it is in fact making liquid chlorine. Liquid chlorine has a very high ph, so you will need to lower the ph most weeks. With using “liquid chlorine” as your sanitizer you will need to add stabilizer threw out the year.
The permanent presence of salt, no matter how small in concentration, can ruin underwater lighting systems, pool liners, the steel walls behind the liner and even the overall masonry work done in/around the pool.
The backwash or waste water that comes from a salt water swimming pool is known to kill plants and dissolve beneficial soil nutrients. As a result, this type of pool has been linked to crop damage in some areas in Australia and even in the US. It is not surprising that there are American towns and localities that prohibit the use of salt water swimming pools. So, you need to first check with local authorities before you invest in this type of swimming pool.
Even with less maintenance, salt water pools need electricity for the chlorine generator to work. A 20,000-gallon pool will require about 500 watts of power. In short, your operating cost for this type of swimming pool will be higher compared to a traditional one.
