Keeping your above ground pool clean is important for maintaining the overall health of your pool. One of the key components to keeping your pool clean is ensuring your pool filter is properly functioning. A dirty filter can cause your pool water to become cloudy and dirty, decreasing the enjoyment of your above ground pool. In this article, we will discuss how to clean your above ground pool filter, including the different types of filters, the cleaning process, and tips for proper maintenance.

Types of Filters

There are three different types of above ground pool filters: sand, cartridge, and diatomaceous earth (DE) filters. Knowing which type of filter your pool has is important when it comes to cleaning and maintenance.

Sand filters utilize sand to filter out debris from the water. These can be the simplest option, requiring backwashing to clean the sand in the filter.

Cartridge filters use a paper filter to remove debris from the water. These filters are easy to maintain and can last for several seasons. However, the paper filters need to be changed frequently to ensure proper functioning.

DE filters use a fine powder made from the shells of microscopic algae that attach to the filter grids. These filters require more maintenance than the other two options but provide the highest level of filtration for your above ground pool.

Cleaning Process

The cleaning process for your above ground pool filter will vary depending on the type of filter you have. Generally, the first step will be to shut off the pump and release the system's pressure. Once you have ensured the pump is off, you can begin to clean the filter.

For sand filters, the backwashing process will flush out the debris caught in the sand. Simply turn your pump back on and reverse the water flow, sending the debris out through the waste outlet.

For cartridge filters, simply remove the filter from the tank and rinse it off using a garden hose. You can also use a filter cleaner to give it a deeper clean. Once it’s clean and visibly clear, you can replace it back into the filter.

Lastly, for DE filters, you will need to remove the grids and hose them down. In order to get them completely clean, you'll need to soak them in a filter cleaner solution. Once complete, you can rinse them and put them back in place.

Tips for Proper Maintenance

In addition to cleaning your above ground pool filter regularly, there are a few things you can do to ensure your filter lasts as long as possible.

First, ensure your pool chemistry is balanced. Unbalanced pH levels can cause build-up within the filter that can lead to reduced effectiveness.

Second, always remember to clean and replace your filters as recommended. Neglecting to do so can lead to reduced efficiency and even damage to your pool.

Lastly, keep an eye on water flow. If you notice that water flow is drastically reduced, it may be time for a cleaning. Catching a dirty filter early can ensure more efficient and cost-effective maintenance.

In conclusion, keeping your above ground pool clean is easy when properly maintaining your pool filter. Regular cleaning and maintenance can prevent costly damage and prolong the life of your filter. We hope this guide helps you properly maintain your above ground pool filter and keep your pool sparkling clean all season long.
