Salt Water Swimming Pools
Salt water pools use salt and titanium electrodes to clean and condition the water. First, a packet containing titanium electrodes is installed on your filter line. Then, you add raw salt to the fresh water of your swimming pool. A standard oval-shaped pool will require around 250kg salt. Once the pool pump kicks on, the salt water is pumped through the filter and over and around the electrode plates, which work by splitting the salt molecules into 2 molecules: Sodium and Chlorine. Usually included is a monitoring kit, which monitors the level of salt and chlorine and indicates when to add more salt.
Fresh Water Swimming Pools
Fresh water swimming pools are filled with basic drinking or tap water, and treated with chemicals to kill bacteria and plants. Fresh water pools need to be monitored for pH levels. The pH levels tell you how much chlorine you need to add in order to make the water safe for swimming. The chlorine needs to be added carefully and consistently in order to create the best conditions for swimming. Too much chlorine will sting the eyes and damage hair. Too little chlorine will allow algae to grow or bacteria to thrive in the water.
Advantages and Disadvantages
Freshwater pools are more in Eurpoe and the United States. They are easier and cheaper to set up, but more difficult to maintain properly. Chlorine smells bad and tends to irritate the skin, hair, and eyes. It also eats away at pool toys and is not considered safe to inhale or be used around children or pregnant women. Salt water pools are more expensive to set up and maintain. Large quantities of salt need to be purchased on a consistent basis. However, salt water pools contain no chemicals. There is no smell, stinging eyes, and the salt level is low enough that the water can be swallowed safely, or even put on nearby plants without harming them. However, these types of pools are harder to find in Europe and America, although they are quite popular in Australia.
