charmshine Aquarium Filter Floss Pad

The charmshine Aquarium Filter Floss Pad is a long white strip of high-density fiber for mechanical filtration. It measures 39.43 x 3.943, and you cut pieces to fit your filter. It catches sediment and fine particles to improve water clarity.

Fluff it first

The floss ships compressed. Soak it in water when it arrives and let it return to a fluffy state before you put it in the filter. Fluffed, the mat is about 1.23 thick. Skipping this step leaves a dense pad that slows flow.

Flow

charmshine lists a 0.25 mesh density, aimed at smooth flow without clogging too fast. It’s a balance between trapping fine debris and letting water pass freely.

Where to use it

• Hang-on filter baskets and canister trays.
• Sump filter socks or trays.
• Pond and water garden filters.
• Turtle tanks, which produce lots of waste.

Cutting tips

Cut each piece slightly larger than the space so it presses against the walls. Gaps let water slip around the pad instead of through it. The narrow strip shape suits slim filter compartments.

Reuse

The fiber resists tearing and can be washed and reused. Rinse in tank water when flow slows, and replace pieces that stay brown or flattened. The floss is listed for freshwater, saltwater and planted setups alike.

Storage

Keep the uncut part dry and sealed so it stays clean until you need the next piece. A strip this long can supply a small filter for many changes.

Layering two thinner cut pieces instead of one thick piece lets you swap the dirtier top layer while keeping the cleaner bottom one in place.
