A saltwater pool is an alternative to a traditional chlorine pool. Although you don't add chlorine tablets to a saltwater pool, it does still contain chlorine. It just has a smaller amount that's generated through the filter system.
A saltwater pool is not a chlorine-free pool. Salt chlorine generators offer an alternative method of sanitizing a pool by using salt to produce its own chlorine automatically. A saltwater pool works much the same way as any other swimming pool, but instead of adding chlorine tablets, you'll add a fine-grain salt.
Many people use liquid chlorine (sodium hypochlorite) or solid chlorine compressed with cyanuric acid (granular or in tablets). In the case of a salt chlorine generator, you use salt (NaCl).
Is a salt water pool better than a chlorine pool? In our professional opinion, YES! Salt water pools are generally lower in chlorine. The chlorine found in saltwater pools are naturally produced from salt, rather than adding harsh liquid chlorine (a.k.a bleach).
Salt water pools are most stable with a pH of 7.6, and Alkalinity of 70-80 ppm. A stabilizer level of 50-80 ppm is recommended by most salt system manufacturers. High calcium hardness levels have no effect on salt water pools, but a level of 180-200 ppm may result in less scale on the salt cell plates.
So, not only is shocking a saltwater pool okay, but it's actually important to your pool's health. Shocking is the process in which you overload your pool with chlorine (3-5 times the normal amount) to improve your pool's cleanliness and kill off organic matter.
Chlorine pools are more traditional and are also cheaper than most saltwater pools. However, they can be more difficult to maintain over time. Because there is no generator making chlorine, you will need to add chlorine into the pool on your own.
A saltwater pool is more expensive than a traditional pool because it requires a higher initial investment. Compared to chlorinated pools, a saltwater pools system is more complex. Both minor and major repairs will call for the expertise of a licensed (and specialized) technician. Saltwater can damage.
For most people, the big selling point for saltwater pools is, well, the salt! The lower-chlorine saltwater is better for swimmers' hair, skin and eyes. Additionally, it also tends to be less harsh on pool toys and swimsuits. So saltwater offers better longevity for your accessories.
Salt Is More Expensive Than Chlorine
Although saltwater pools require a different generator than chlorine pools, chlorine is actually much more expensive than salt is. This is especially true with the chlorine shortage happening right now.
