Many pool owners find themselves in a confusing situation. Their pool water has turned green and suddenly they no longer want their family/ friends to dive in. What is the right thing to do? First and foremost, let’s learn the top reasons why pool water turns green in the first place.

Green pool water is an indication of high algae/ bacterial growth. A green pool is seen as unhygienic. However, there are several reasons why this occurs and how to select the right service for help. Maintaining your pool with a reputable service company is the best way to save money longterm.

Poor Filtration

Poor filtration is the main culprit of green pool water. A pool’s filter is responsible for filtering and removing various debris and algae. The 4 types of filters are sand, glass, cartridge and DE. Depending upon which type of filter you have, the filtration’s ability to remove toxins will vary. The biggest threat to proper filtration is clogged or broken filters. For this reason, contacting a knowledgeable professional is essential.

Unbalanced pH

The pH of pool water must be between 7.2 and 7.8. This is considered a normal and “healthy” range. A pH lower than this means chlorine is not working effectively in the pool. This can lead to rapid bacteria and algae growth. If the pool turns too acidic, metals and plastics will become corroded in the water.

Phosphate

When the pool is not properly cleaned, phosphate will buildup. These organic debris will amass and add to phosphorus in the pool. With the inevitable heat of summer, algae grows on the debris.
