How to Clean Above Ground Pool Filter Cartridge

Maintaining an above-ground pool requires regular cleaning of different components, including the pool filter cartridge. It's essential to keep the filter cartridge clean to ensure proper pool water filtration and prevent potential damage to the filtration system. Without regular cleaning, the cartridge may clog or develop algae, reducing its effectiveness in removing impurities from the pool water. This article provides a comprehensive guide on how to clean above-ground pool filter cartridges to ensure your pool stays clean all season.

1. Step by Step Process of Cleaning an Above Ground Pool Filter Cartridge

Before starting the cleaning process, ensure that you turn off the filtration system and disconnect the filter cartridge from the pool pump. Next, remove any debris or contaminants that might have accumulated on the cartridge's surface using a soft brush or a garden hose. Then, fill a bucket with water and add some cleaning solution or detergent. Soak the filter cartridge in the solution and leave it to soak for some time to allow the solution to penetrate to the pores of the filter cartridge.

After soaking, rinse the filter cartridge thoroughly using a garden hose or a pressure washer. It's essential to rinse the cartridge thoroughly to remove any remaining cleaning solution or detergent. If you leave the filter cartridge to dry with any residue present, it may damage the cartridge's material and reduce its effectiveness in cleaning the pool water.

2. Using Muriatic Acid to Clean the Cartridge

Apart from using cleaning solutions, you can also use muriatic acid to clean your above-ground pool filter cartridge. However, it's essential to handle muriatic acid with caution and adhere to the recommended safety measures. Start by preparing a solution of water and muriatic acid in a bucket or a plastic container. Add a half a gallon of acid to ten gallons of water and stir to mix.

Place the filter cartridge in the solution and let it soak for no more than 15 minutes. After soaking, rinse the cartridge thoroughly with water to neutralize the acid solution before reinstalling it. Remember to wear gloves, safety goggles, and protective clothing when handling muriatic acid.

3. How to Maintain Your Above Ground Pool Cartridge

Routine maintenance is crucial to ensure your above-ground pool filter cartridge functions optimally throughout the season. Here are some tips on maintaining your pool filter cartridge:

- Clean the filter cartridge at least once every four weeks or as needed, depending on pool usage.

- Don't use high-pressure nozzles or scrubbing tools when cleaning your pool filter cartridge as these could damage the paper material.

- Avoid using oil or grease-based cleaning solutions or those containing bleach, acid, or household cleaners.

- Replace your pool filter cartridge at least once a year or when it shows signs of damage or wear.

- Ensure that you correctly install the filter cartridge and properly connect it to the pool pump to maximize pool water filtration.

4. Why is Cleaning Your Filter Cartridge Important?

Cleaning your above-ground pool filter cartridge is a critical aspect of maintaining a clean and healthy swimming pool. When the filter cartridge is dirty or clogged, it is less efficient at removing impurities from the pool water, leading to cloudiness and a greenish appearance. Additionally, a dirty pool filter cartridge can strain your pool pump, leading to mechanical damage and expensive repairs. Maintaining your pool filter cartridge ensures effective pool water filtration and saves you money in the long run.
