Can you kill green algae by filling an above ground pool with salt water?

It is possible to kill green algae in an above ground pool by filling it with salt water. Saltwater pools use a chlorine generator that converts salt into chlorine, which kills algae and bacteria. The salt concentration in a saltwater pool is typically around 2,500 parts per million (ppm), which is much lower than the salt concentration in the ocean. This means that saltwater pools are not as corrosive as saltwater pools containing seawater.

There are a few benefits to using saltwater in an above ground pool. First, if the pool is covered when not in use, the chlorine generator will continue to produce chlorine, which helps to keep the pool clean and free of algae. This can reduce the amount of time and money spent on pool maintenance. Second, saltwater pools are less likely to cause skin and eye irritation than chlorine pools. This is because the chlorine in saltwater pools is generated naturally, rather than being added directly to the pool. Finally, saltwater pools are more environmentally friendly than chlorine pools. This is because the chlorine in saltwater pools does not evaporate into the atmosphere, which reduces the amount of chloramines released into the environment.

However, there are also a few drawbacks to using saltwater in an above ground pool. First, saltwater pools can be more expensive to set up than chlorine pools. This is because the saltwater pool system includes a chlorine generator, which is also a salt pool chlorinator. Second, saltwater pools can be corrosive to metal surfaces, such as the pool ladder and the pool deck. This is why it is important to use saltwater-resistant materials when building an above ground pool.

Overall, saltwater pools can be an effective and environmentally friendly way to keep an above ground pool clean and free of algae. However, it is important to weigh the benefits and drawbacks before deciding if a saltwater pool is right for you.
