In a warm climate like Florida, a swimming pool is a welcome respite from the heat. The feature can offer years of enjoyment for your family members and friends, acting as the focal point of parties and barbecues. However, algae can be a real problem that dampens the summer fun. Luckily, understanding what causes it and how to prevent it will keep your pool clean for the whole season. 

What Causes Algae and Why Is It Bad?

Wind, rain, and debris introduce small algae spores into a pool. They can bloom after a few hours, especially if the water receives direct sunlight and is warm, making the pool appear green and cloudy. 

While not dangerous to swimmers, it can cause pool surfaces to become slippery and negatively affect their depth perception. The substance is also known to clog filters, requiring more frequent filter replacement. 

What Are the Types of Algae and How to Remove Them?

Three main types of algae can grow in your pool: green, yellow, and black. Green algae is the most common and can be easily identified by its bright green color. Yellow algae is a bit harder to detect, as it appears as small patches on pool surfaces. Black algae is the most difficult to remove, as it grows in the cracks and crevices of pool surfaces.

If you notice algae growing in the pool, check the filtration and pool pump equipment as soon as possible and ensure they are up and running. Turn off the pool heater if you have one, as warmth can encourage growth. Vacuum and brush the pool daily until the algae clears. If the algae persists, call a professional to clear it. 

How Can You Prevent Algae in the Future?

Keep your swimming pool water circulating so algae doesn’t have a chance to bloom. When possible, cover the feature to keep spores out. You also need to test and maintain chlorine levels regularly. Levels between 2.0 and 4.0 parts per million (ppm) are strong enough to kill spores before they bloom. Shock the pool once a week to provide additional support.
