Algae are common organisms that can grow in several different bodies of water, including swimming pools. Many pool owners worry about algae growing in their pool for a few reasons. First, algae can cause your pool’s water to become cloudy or change color, making it difficult to find the source of the algae and completely eliminate it. Algae are also a health hazard and may contain or attract other pathogens like the E-coli bacteria. Finally, algae can result in expensive pool repairs. They clog the pores of pool filters which decreases filtration and can possibly cause enough damage that you’ll need to replace your filter system or pool liner.

There are several different types of algae, categorized by color, including green, black, pink and yellow algae. In order to keep your swimming pool from becoming infested with these different types of algae, it is important to know the different ways it can begin to grow and spread. The most common ways for algae to develop are unbalanced chemicals and pH levels, lack of proper filtration, unused and uncovered pools on warm and sunny days, and dirt particles gathering at the bottom of your pool. There’s no secret to how you can prevent algae from growing in your pool. The key is proper pool maintenance! Here are simple ways that you can prevent algae from growing in your swimming pool:

  • Check water chemical levels at least every few days but more often is better. Use testing strips to assess the chemical and pH level in your swimming pool on a regular, or even daily, basis.

  • Filter your swimming pool water daily. Algae starts to grow in your pool’s small crevices and dark areas which is why it is necessary to properly filter and circulate your pool’s water every day.

  • Remove dirt and debris from your swimming pool. Algae cling to dirt particles and quickly start to spread which is why it’s necessary to keep as much dirt out of your pool as possible. Vacuuming helps remove particles, but algaecides are a great way to prevent any kind of algae growth.

  • Use a special brush that is safe to use on your vinyl swimming pool liner to sweep the sides and bottom of your pool. Lightly brushing the walls of your pool every year or so will help reduce the risk of algae growth.

  • On sunny days, cover your swimming pool with a solar cover. Algae grow faster on warm days because the sun provides the organisms with food. Some light is good, but a cover will help reduce the chance of algae growth.

Algae are nasty, organisms that spread quickly. Keep these pool maintenance tips in mind when you’re cleaning your swimming pool so you don’t have to deal with the hassle, cost and frustration of algae growth.
