will pool filter remove algae

Introduction

If you have a swimming pool or you are planning to get one, learning about how pool filters work and what they can do for you is essential. The importance of pool filters in the maintenance of a swimming pool cannot be overstated. But one of the common questions new pool owners ask is: will pool filter remove algae? That is precisely what we are going to talk about in this article.

What Is Algae?

Algae are a group of simple, non-flowering, and often aquatic plants, including seaweeds and many single-celled forms. It is commonly found in water or moist environments when the conditions are suitable, such as warm temperatures, sunlight, and enough nutrients for growth. It produces chlorophyll, which gives it a green color, allowing it to produce its food via photosynthesis.

Types of Algae in Swimming Pools

There are three main types of algae commonly found in swimming pools: green algae, yellow or mustard algae, and black algae.

Green Algae: This is the most common type of algae found in swimming pools. It is usually easy to spot, appearing as green slime on pool walls or surface. It can grow quickly and covering a large part of the pool within a short time if not treated immediately.

Yellow or Mustard Algae: This type of algae is usually difficult to treat since it is resistant to normal chlorine levels. It can appear as yellow, brown, or tan on pool walls or floor and is usually slimy.

Black Algae: This is the most severe of all algae infestations. It is typically black, gray or dark blue with a hard, almost impenetrable head. It can grow under pool tiles and plaster and can be challenging to remove.

Can a Pool Filter Remove Algae?

The answer is yes. Pool filters can remove algae to an extent, depending on the type of filter you use, its effectiveness, and the amount of algae present. However, it's crucial to keep in mind that some species of algae are highly resistant to chlorine and other traditional pool chemicals, so a pool filter may not always offer an adequate solution. Hence, other treatment options may be necessary to eradicate algae entirely.

The Role of a Pool Filter in Removing Algae

Pool filters play an essential role in keeping the pool water clean and free of impurities, including algae. The three types of pool filters are sand filters, cartridge filters, and diatomaceous earth (DE) filters.

Sand Filters: This type of filter utilizes graded silica sand as the filter medium. It works by forcing the water through the sand layer, trapping dirt, debris, and other impurities. While sand filters are not effective in removing fine particles or microscopic organisms, they can remove larger algae particles that can be captured by the sand.

Cartridge Filters: These filters have a pleated or folded filter fabric that removes impurities by capturing them within or on the filter medium. Most cartridge filters can capture particles down to 10 microns, which is smaller than the diameter of a human hair. They can effectively filtrate larger algae particles, but not smaller ones.

Diatomaceous Earth Filters: This type of filter utilizes a powder known as diatomaceous earth, composed of microscopic fossilized diatoms as the filter medium. It works by coating a pre-coat of DE over a mesh or grid filter, and water passes through it, trapping impurities including algae. DE filters can remove particles as small as 5 microns and are highly efficient in removing algae particles.

Conclusion

In conclusion, pool filters can remove algae to some extent but may not be the best or the only solution for severe algae infestations. Proper pool maintenance practices, such as regular cleaning and chemical treatment, can help to prevent algae growth in the first place. The best course of action when dealing with persistent algae infestations is to seek the advice and assistance of a professional pool service.
