What to Look For Before Buying

Picking the right media depends on your existing setup. Consider your hardware, how much time you have for cleaning, and your water quality goals.

Check Filter Compatibility

Verify if your filter system uses sand, DE, or cartridge media. Sand filters are the most versatile, as they can accept glass or synthetic balls. DE filters require specific diatomaceous earth powder. Always confirm that your chosen media matches your hardware.

Value Maintenance Requirements

Consider how much time you want to spend maintaining the filter. Synthetic balls need manual cleaning, while sand is backwashed. DE requires careful handling of fine powder. Choose a media that fits your available time and physical capability.

Rating Filtration Precision

Check the micron rating. A lower number means better clarity. If your pool gets lots of pollen, go for lower microns.

Verify Environmental Impact

Look for reusable options. Glass and fiber balls last longer than sand, which reduces waste and saves money over time.

Frequently Asked Questions

Can I use filter balls with any sand filter?

Yes, they fit most standard sand tanks. Just be sure to remove all the old sand first.

How often should I clean synthetic filter balls?

It varies, but once a month is usually fine. Just use the mesh bag provided to wash them.

Are pool clarifiers compatible with filter balls?

No, avoid liquid clarifiers. They cause the fibers to stick together and will ruin your filtration.

Does DE filter media expire?

It does not expire, but it clumps if it gets wet. Keep it in a dry, sealed container.

Is glass media better than sand?

Yes, it filters better, lasts longer, and is much lighter than sand, which makes it a great upgrade.
