обыкновенная соль морская или нет в громаднейших мешках продается в спец магазине или в обыкновенном Home Depot, высыпаешь и там какой то процесс идет и она вырабатывает хлорин, час вам ссылку дам, мне так не обьяснить http://phoenix.about.com/cs/wet/a/saltpool01.htmBut what is the real difference from a salt water pool vs. chlorine option? Here is a quick run-down of the pool battle:Salt water is more comfortable for swimmers. Don't be fooled into thinking that there is no chlorine in these pools. There is. However, in a salt water pool vs. a chlorine pool, the level of chlorine needed is lower and the pH level can be a bit higher. That means the pool water does not cause burning, itching, dry skin, or green hair. It also smells and tastes better.These pools are less expensive to maintain. A salt water pool vs. chlorine pool is a lot cheaper over time because you do not have to add chlorine tablets to the water. Instead, you just add salt! The salt water runs through and electrical system that charges the salt and creates chlorine on its own. It is initially more expensive to maintain, but in only a few summers, it will pay for itself. After all chlorine tablets cost $60 or more per bucket and you'll only need about $20 worth of salt every summer, in most cases.It is, in general, less time consuming to maintain these pools. A salt water pool vs. chlorine pool eats up less of your time because the control box, which charges the salt, regulates most of the water levels. Once you learn the system, you can easily control it, even when you go away on vacation by setting up a timer. However, be aware that you'll still have to check the water for pH levels as well as calcium levels.Both salt water and chlorinated water are unhealthy for the environment. No one really wins the pool war when it comes to environmental concerns. While salt water may be a bit safer, it can still cause soil and drinking water problems, as well as kill sensitive plants around the pool. On the plus side, a salt pool option is safer for pets and for your family.
