Does Algae Clog Pool Filter?

Having a pool means endless fun, relaxation, and relief from the summer heat. However, it also requires maintenance and cleaning to keep it crystal clear and free from any contaminants. One of the most essential parts of maintaining a swimming pool is the filter system, which ensures that the water remains safe and clean. However, even with regular maintenance, pool filters can still become clogged, especially when dealing with algae. So, does algae clog pool filter, and how can you prevent it from happening?

What is Algae?

Before we answer the question, let's first define what algae is. Algae are simple, aquatic organisms that can range from single-celled to multi-celled organisms. They can be found in both saltwater and freshwater and can flourish in a variety of living conditions. Algae can grow at alarming rates and can quickly turn your pool from an oasis to a murky green mess.

What Causes Algae in Pools?

Several factors can contribute to the growth of algae in pools, including warm weather, high humidity, inadequate circulation, and a lack of sanitizer or pool shock treatment. Algae can also form when the pH, alkalinity, or calcium hardness levels in the water are unbalanced. The most common types of algae found in pools are green, yellow, and black.

Does Algae Clog Pool Filter?

The short answer is yes. Algae can clog your pool filter, reducing its effectiveness and possibly causing damage to the filtration system. Algae can hinder the flow of water through the filter media, making it more difficult for water to be cleaned and return to the pool. Additionally, when the algae dies, it can cause it to clump together, forming bigger particles that can quickly clog your filter.

How to Prevent Algae from Clogging Your Pool Filter?

The best way to prevent algae from clogging your pool filter is to ensure that your pool's chemical levels are balanced. You should test the water regularly and adjust the pH, alkalinity, and sanitizer levels as needed. Additionally, you can add algaecide to the pool on a regular basis to prevent algae growth. A thorough brushing and shock treatment can also help prevent the growth of algae in your pool.

What to Do if Your Pool Filter is Clogged with Algae?

If your pool filter is already clogged with algae, you'll need to clean or replace the filter. To clean the filter, you'll need to backwash it to remove any debris and buildup. If your pool filter is too clogged to backwash, you may need to chemically clean it or replace the filter media altogether.


Algae growth in pools is a common problem that can be prevented through regular maintenance and care. Whether it's brushing your pool, balancing its chemical levels, or adding algaecide, taking preventative measures is crucial in keeping your pool free from algae and ensuring that it runs smoothly all summer long. And remember, if your pool filter does become clogged with algae, it's not the end of the world – there are many ways to clean or replace it and get your pool back to its pristine condition.
