Does Pool Filters Remove Algae: The Truth You Need to Know

Pools are a great addition to any home that wants to add a lot of fun and entertainment to their backyard. However, one thing that every pool owner despises is the growth of algae in their pool. Algae can turn a perfectly clear and clean-looking pool into a murky, green mess that is unappealing to swim in. While there are a number of different products and methods to remove algae from your pool, the question remains – does your pool filter remove algae? In this article, we will take a look at how pool filters work and whether or not they are effective in removing algae.

Understanding How Pool Filters Work

Before we delve into whether or not pool filters remove algae, it is important to first understand how pool filters work. Most pools are equipped with a filtration system that consists of a pump and a filter. The pump is responsible for pulling water from the pool and sending it through the filter. The filter, which is usually made of sand, diatomaceous earth, or some other type of granular substance, is responsible for removing debris, dirt, and other impurities from the water before it is sent back into the pool.

There are three main types of pool filters: sand filters, cartridge filters, and diatomaceous earth (DE) filters. Sand filters use sand as the filter medium, while cartridge filters use a pleated filter made of polyester or other materials. DE filters use a powder made from diatomaceous earth as the filter medium. Each type of filter has its own unique way of removing impurities from the water.

Do Pool Filters Remove Algae?

The short answer to whether or not pool filters remove algae is yes, but with a caveat. While pool filters are designed to remove debris and other impurities from the water, they are not always effective at removing algae. The reason for this has to do with the size of the algae cells.

Algae cells are relatively small and can easily pass through the filter medium of most pool filters. While the filter may catch some of the larger pieces of algae, the majority of the cells will slip through the filter and continue to grow and multiply in your pool. This is why it is important to take other steps to prevent and remove algae growth in your pool, in addition to using your pool filter.

Other Ways to Prevent and Remove Algae from Your Pool

So, if pool filters are not always effective at removing algae, what else can you do to keep your pool clean and clear? Here are some additional steps you can take:

1. Regularly test your pool water and maintain proper chemical levels. Proper chemical levels can prevent algae growth before it even starts.

2. Keep your pool clean by regularly skimming the surface and brushing the walls and floor of the pool.

3. Shock your pool regularly to kill any algae that has already started to grow.

4. Use an algaecide to prevent algae growth in the first place.

5. Consider adding a UV system or an ozone generator to your pool. Both of these systems can keep bacteria and algae in check by killing them with UV light or ozone.

Conclusion

While pool filters can help remove some of the larger pieces of debris and algae from your pool, they are not always effective at removing all of the algae cells. To keep your pool clean and clear, it is important to use your pool filter in conjunction with other preventive and corrective measures. By doing so, you can enjoy a crystal-clear pool all season long.
