How to Acid Wash Pool Filter: A Step by Step Guide

Swimming pools are a source of enjoyment for many people, but keeping the pool clean is an essential task. The pool filter plays the most critical role in maintaining the freshness and clarity of the pool water. Over time, the pool filter may accumulate dirt, debris, and mineral deposits, reducing its effectiveness. This is why it is essential to acid wash the pool filter regularly to ensure it works efficiently.

In this article, we will provide you with a step-by-step guide to acid washing your pool filter. We will also discuss the necessary safety measures you should take to prevent harm to yourself and the environment.

1. Gather the necessary materials

Before beginning the acid wash process, you need to gather the necessary materials. These include safety goggles, a rubber glove, pH indicator strips, a hose, a large cleaning bucket, a sponge, and muriatic acid. Remember to wear protective clothing, including long sleeves and pants, to avoid skin contact with the acid.

2. Remove the filter

The first step is to turn off the pool pump and remove the pool filter from the pump basket. You need to be cautious when handling the filter, as it may contain sharp edges that can cut your hand.

3. Rinse the filter

Now that the filter is out of the pump basket, you must rinse it with running water to remove visible debris and dirt. Use a high-pressure hose to achieve the best results. Rinse the filter until you can see through the filter material. After rinsing, inspect the filter for any cracks or damage.

4. Check the pH level

Before using the muriatic acid, you must check the pH level of the pool water. The pH of the water should be around 7.2 to 7.8. If the pH is below 7.2, add soda ash to increase its level. But if it is above 7.8, add muriatic acid to reduce its level.

5. Dilute the muriatic acid

It's essential to dilute the muriatic acid before using it. To dilute the acid, add one part of the acid to ten parts of water in the cleaning bucket. Always add the acid to the water, not vice versa, to prevent the acid from splashing around.

6. Soak the filter

Once the acid is diluted, you can soak the filter in the solution overnight. Make sure the filter is entirely immersed in the solution. The muriatic acid solution will dissolve the mineral deposits, dirt, and debris clogging the filter. Don't leave the filter in the acid solution for more than twenty-four hours, as it may damage the filter material.

7. Rinse the filter

After soaking the filter, take it out of the solution and rinse it with running water. Use a high-pressure hose to remove remaining dirt and debris. Rinse the filter until the water running through it is clear.

8. Reinstall the filter

Once the filter is clean, you can reinstall it back into the pump basket. Ensure that all the gaskets, o-rings, and nuts are correctly positioned.

In conclusion, cleaning the pool filter is essential to maintain the cleanliness and clarity of the pool water. The acid wash process removes dirt, debris, and mineral deposits from the filter, ensuring peak performance. Always remember to wear protective clothing, gloves, and goggles when handling muriatic acid. With the above step-by-step guide, you can acid wash your pool filter safely and efficiently.
