How to Use Marina Polywool

1. Take a suitable amount of polywool from the pack.
2. Place it inside the mechanical filtration section of your aquarium filter.
3. For multi-stage filters, position the polywool after coarse mechanical media to capture finer particles.
4. Ensure water can pass freely through the material without restricting filter flow.
5. Inspect regularly and replace when heavily clogged or no longer filtering effectively.

Helpful Tip: Avoid packing filter wool too tightly, as restricted water flow can reduce filtration performance. Polywool is best used alongside established biological filter media rather than as a replacement for it.

When Should You Replace Aquarium Filter Wool?

Check your polywool during regular aquarium maintenance. Replace it when it becomes heavily loaded with debris or begins restricting water flow. Replacement frequency depends on your aquarium's stocking levels, feeding and overall filter setup.

Regular maintenance helps your filter continue operating efficiently while keeping suspended debris under control.
