How to Add Flocculant to Above Ground Pool: Clear Water Guide

Adding flocculant to your above ground pool is a crucial step in maintaining clean and clear water. Flocculant, also known as flocculants or flocking agents, is a chemical substance that helps to gather together fine particles in the water, making it easier to remove them through the filtration system. By using flocculant correctly, you can effectively clarify your pool water and enjoy a sparkling clean swimming experience. Here is a step-by-step guide on how to add flocculant to your above ground pool:

Step 1: Test Your Pool Water

Before adding flocculant to your above ground pool, it’s essential to test the water to determine the current levels of pH, alkalinity, and chlorine. You can use a pool water testing kit to get accurate readings. Make sure the pH and alkalinity levels are within the recommended range before proceeding with the flocculant treatment.

Step 2: Choose the Right Type of Flocculant

There are different types of flocculants available in the market, including liquid, granular, and tablet forms. Depending on your pool’s size and the severity of the cloudiness, choose the appropriate type of flocculant for your above ground pool. Follow the manufacturer’s instructions on the product label for the correct dosage.

Step 3: Prepare the Flocculant Solution

Prepare the flocculant solution according to the instructions provided on the product label. In most cases, you will need to dilute the flocculant in a bucket of water before adding it to the pool. Stir the solution well to ensure proper mixing of the flocculant.

Step 4: Turn Off the Pool Pump

Before adding the flocculant to your above ground pool, make sure to turn off the pool pump. This will allow the flocculant to work effectively by settling the particles to the bottom of the pool without being circulated back into the water.

Step 5: Add the Flocculant to the Pool

Slowly pour the prepared flocculant solution around the edges of the pool while walking around the perimeter. This will help distribute the flocculant evenly throughout the pool water. Avoid pouring the flocculant directly into the skimmer or the filter system.

Step 6: Let the Flocculant Settle

After adding the flocculant to the above ground pool, allow it to settle for at least 6 to 8 hours or overnight. During this time, the flocculant will work to clump together the fine particles in the water, forming larger particles that can be easily removed through the filtration system.

Step 7: Vacuum the Pool

Once the flocculant has had enough time to settle, use a pool vacuum to remove the settled particles from the bottom of the pool. Slowly vacuum the pool floor, moving in overlapping strokes to ensure thorough cleaning. Make sure to clean the filter afterwards to remove the captured debris.

Step 8: Backwash the Filter

After vacuuming the pool, it’s important to backwash the filter to remove any remaining debris and contaminants. Follow the manufacturer’s instructions for your specific filter type to properly backwash the system and restore optimal filtration efficiency.

Step 9: Test the Water Quality

Once you have completed the flocculant treatment and filtration process, test the water quality again to ensure that the pH, alkalinity, and chlorine levels are balanced. Adjust the chemical levels if necessary to maintain clear and clean pool water.

Step 10: Maintain Regular Pool Maintenance

To prevent cloudiness and maintain crystal-clear water in your above ground pool, it’s important to establish a regular maintenance routine. This includes checking and adjusting chemical levels, cleaning the pool filter, skimming the surface for debris, and vacuuming the pool regularly.


Adding flocculant to your above ground pool is a simple yet effective way to clarify the water and remove fine particles that cause cloudiness. By following the steps outlined in this guide and maintaining a consistent pool maintenance schedule, you can enjoy a sparkling clean pool that is inviting and refreshing for swimming. Remember to always read and follow the manufacturer’s instructions when using flocculant or any other pool chemicals to ensure safe and effective treatment of your pool water.
