Why is Green Pool Water Common in Louisiana?

Posted by Lucas Firmin on Apr 11, 2023 2:08:29 PM

Louisiana is known for its hot and humid temperatures and frequent afternoon thunderstorms, but did you know it's also the second wettest state in the country? According to, Louisiana receives roughly 60 inches of precipitation each year, which can pose unique challenges for residential pool owners.

Heavy rain can dilute pool chemicals, especially in high temperatures and humid conditions, as in Baton Rouge. This chemical imbalance can lead to your pool water turning green due to insufficient chlorine levels. If left untreated, this can result in unsanitary and unhealthy water.

So, why does pool water turn green after it rains? The short answer is that more chlorine is needed in the pool, but the issue is often more complex than that. Algae, which causes pool water to turn green, quickly spreads unless addressed. Algae blooms can occur when a pool has low free chlorine or when exposed to high heat or heavy rain.

Dealing with pool algae can be a frustrating and challenging experience for residential Baton Rouge pool owners. Acting fast if you notice the early stages of algae growth is essential, as it can quickly multiply into a full-scale bloom. Regular testing of pool water and proper maintenance of pool filtration systems can help prevent algae growth from occurring.

The most effective preventative measure for curtailing the growth of algae is to regularly brush the walls of your pool, no less than once a week. However, it is recommended to increase the frequency of brushing to ensure optimal algae prevention. It is imperative to remain vigilant and proactive in your efforts, regardless of whether or not the algae is visibly present, as it can manifest in a transparent state.
