why is my pool filter blowing out white

Have you noticed that your pool filter is blowing out white substances? If so, you may be wondering what is causing the issue and how to fix it. Here's everything you need to know about why your pool filter may be blowing out white and what you can do to remedy the problem.

1. What is the White Substance?

First and foremost, it's essential to understand the white substance that's being blown out of your pool filter. Typically, it's either dead algae or calcium deposits that have built up inside of the filter. These substances can make their way back into the pool, giving the water a cloudy appearance and making it less inviting for swimming.

2. The Cause of White Substances in Pool Filters

The primary reason for the white substance buildup is typically caused by an imbalance of your pool's chemicals. When your pH levels are too high, mineral deposits such as calcium can become lodged inside the filter cartridges. When your pH levels are too low, the water can become more acidic and cause algae growth, which can eventually settle and clog up the filter.

3. How to Fix this Issue

To begin, it's necessary to test your pool's pH levels. A pH of 7.2-7.6 is optimal for a pool, and anything outside of that range can lead to complications with the water. If your pH levels are off, consider adding pool chemicals to rebalance them.

If the filter has a blockage, you can try manually cleaning it. You will typically need to disassemble the filter and use a hose with high pressure to remove any debris that has built up inside. A filter cleaner can also be used to dissolve any calcium or mineral deposits that have accumulated within the filter.

4. The Importance of Regular Maintenance

To prevent white substances from building up in your pool filter, regular maintenance is essential. This includes testing your pH levels weekly, using pool chemicals and keeping your filter clean.

In addition to regular maintenance, there are two other solutions you can utilize to prevent white substances from building up:

- Cleaning Your Filter More Often: Depending on the type of pool filter you have, it is important to clean it often. For instance, sand filters may need to be back-washed once per week, while cartridge filters may need to be replaced or cleaned every three to four months.

- Utilize a Stain and Scale Preventative: A stain and scale preventative can reduce buildup on the filter and make removing existing calcium buildup easier. Some preventatives are designed specifically for pool filters, and they can be added to the filter, skimmer, or pool water.

5. Solution to Consider: Installing a Saltwater System

Saltwater systems are a popular choice for pool owners as they help to eliminate the need for chemicals and maintain a consistent pH balance. The salt in the water is broken down into chlorine, which helps to keep the water clean and reduce the likelihood of mineral buildup.

By installing a saltwater system, pool owners reduce the chances of white substance buildup, clogged filters, and cloudy water. Plus, the water is much gentler on the skin and eyes, which is a bonus for swimmers.

In conclusion, if you notice your pool filter is blowing out white substances, don't panic. By testing your pH levels regularly, cleaning the filter more often, and utilizing a stain and scale preventative, you can reduce the likelihood of mineral buildup and improve the cleanliness of your pool. Utilizing a saltwater system is also a worthwhile solution to prevent this issue from occurring in the future, so make sure to consider it as an option.
