Why Is My Pool Green?

You’ve seen those swimming pools in Jacksonville, Florida with an unsightly green tinge, and now the same thing is happening to your pool. Pools can even turn green overnight, providing a nasty shock when you visit the backyard.

Why is my pool green? What’s going on? 

Pools turn green when they experience a buildup of algae, which thrives in pools with low chlorine levels. If you forgot to apply your usual chlorine treatment, experimented with a different amount of chlorine or went on an extended vacation and forgot to schedule pool cleaning while you were away, you might find a green pool.

The exact hue of green can help you determine how to solve this problem. If your pool is light green or teal, you’ve got a minor algae problem. If your pool is green to dark green, you have a standard algae problem.

Treating your pool

Pool shock treatments add high amounts of chlorine to restore your pool’s pH level and kill the algae. Treat lightly contaminated pools with 2 pounds of pool shock per 10,000 gallons of water. For a pool with standard algae growth, increase the pool shock to 3 pounds per 10,000 gallons of water. For a pool that is highly contaminated, try 4 pounds of shock per 10,000 gallons of water.

The shock will kill the algae, turning your pool a cloudy hue of grey, blue or white. Run the pool’s filtration system to filter the dead algae out of the pool and clear up the water. Contact your local swimming pool company in Jacksonville, Florida, All Seasons Pools, for more tips on killing algae.
