Will a brass fountain standing in pool affect the pH level salt water pool?

Yes, a brass fountain standing in a saltwater pool can affect the pH level of the pool water.

Brass is an alloy of copper and zinc. When brass is exposed to water, the copper and zinc ions can dissolve into the water. This can increase the metal content of the pool water, which can in turn affect the pH level.

The pH level of a pool should be between 7.2 and 7.8. If the pH level is too low, the water can become corrosive and damage the pool equipment. If the pH level is too high, the water can become cloudy and form scale deposits.

The dissolved copper and zinc ions from the brass fountain can raise the pH level of the pool water. This is because copper and zinc are both metals that are more reactive than hydrogen. When these metals dissolve into the water, they release hydrogen ions (H+). This reduces the concentration of hydrogen ions in the water, which raises the pH level.

The amount of dissolved copper and zinc ions that are released into the pool water will depend on the size of the fountain, the composition of the brass, and the temperature of the water. In general, the larger the fountain, the more copper and zinc ions will be released. The higher the water temperature, the more copper and zinc ions will be released.

If you have a brass fountain in your saltwater pool, you should test the pH level of the pool water regularly and adjust it as needed. You may also want to consider using a metal sequestering agent to prevent the dissolved copper and zinc ions from affecting the pH level.
