Imagine wanting to go for a dip in your pool, only to be greeted by green pool water. Gross! Not only is green water unsightly, but it’s probably also hazardous to swim in. The thing is, what’s causing the pater to turn green? And what can you do about it?

Not Enough Chemicals

The biggest reason why pool water turns green is because of algae growth, which is commonly caused by lack of sufficient chlorine levels or other pool water cleaner that’s being used. If the chemical levels are off, algae growth can get out of control, eventually turning the water green. 


Another potential cause for green pool water is the presence of metals, more often copper. There can be a number of ways that metals are introduced to the pool water, such as acidic water, algaecides, source water, or from the metal components of the swimming pool.

When you shock the pool when metals are present in the water, they will oxidize, which can turn the water green. If you do not treat this problem right away, the issue will persist and worsen, eventually staining the finish of the pool. 


Your pool water may have turned green because of the presence of pollen from plants or trees that are close to the pool. Filters are not usually able to catch pollen because the particles are too small, so it ends up accumulating in the water and turning it green. The good news is that although unattractive, pollen in pool water is usually harmless.
