Understanding pool chemistry is tricky, especially when it comes to making sure your swimming pool has the perfect pH balance. Crystal clear water is always the goal, so it’s essential to figure out what is causing algae growth in your pool and how to manage it.

Wind, rain, and other contaminated objects can carry algae spores to your pool. Algae grows in pools rapidly because of the warm and humid environments, but does pool algae like high or low pH? While you can’t put a stop to the spores entering your pool, you can take steps to prevent them from spreading and turning your pool into a green swamp that’s sore for the eyes.

Most Algae Grows in High-pH Environments

Most types of algae typically enjoy higher pH levels, ranging from 8.2 to 8.7. Once algae starts growing, it can further raise the pH level in your pool and cause more algae growth. Algae feeds off of CO2, which your pool needs in order to maintain a healthy chemical balance.

Some Algae Grows in Low pH

Having a low pH level in your pool means your water is too acidic. Algae growth varies because not all algae live in acidic conditions. Water with a low pH balance is also harmful to your filter, allowing more algae spores to enter your pool.

How to Prevent Algae Growth In Your Pool

Now that you know the answer to “does pool algae like high or low pH?” you can take steps to prevent algae growth. Here’s how you can get rid of the green algae on your pool walls.

Balance Your Chemical Levels

Test your pool water to identify your pool’s pH level. From there, adjust the chlorine level to raise or lower the pH level, giving it the proper balance, anywhere from 7.2 to 7.6.

Install an Appropriate Filtration and Circulation System

Pool pumps are a vital aspect of your pool because they keep the water circulating. This means water constantly moves through your pool and equipment, helping filter out any unwanted algae blooms.

Incorporate Regular Cleaning and Maintenance

Whether you use interior brushes, a pool vacuum, or an automatic pool cleaner, consistent maintenance helps reduce the amount of algae in your pool. Algae often forms on pool walls, steps, and floors, so incorporate a regular cleaning schedule for your pool to make it most appealing.
