AQUANEAT Aquarium Canister Filter Pads, 9-Pack Bio Sponges in Three Densities

AQUANEAT replacement aquarium canister filter pads provide mechanical and biological filtration, with nine sponge pads in coarse, medium, and fine densities.

• Compatible with selected SUNSUN, Polar Aurora, and CF-500 filters — fits several named canister filter models.
• Traps most visible debris without restricting water flow — helps filter aquarium water while maintaining flow.
• Reusable after rinsing — lets you clean the pads for continued use.
• Vacuum-sealed for packaging — soak the pads in water so they expand to normal size.

These replacement sponges are made for aquarium owners maintaining a compatible canister filter. Their different densities provide a choice of sponge media, while the pads are designed to contribute to both mechanical and biological filtration. Use the compatibility details below to match the set to your filter model.

Which canister filters are these pads compatible with?

AQUANEAT filter pads fit SUNSUN HW-304B, HW-404B, and HW-704B canister filters. Compatibility also includes the SUNSUN HW-3000, Polar Aurora 525gph, and CF-500.

• Also fits the Polar Aurora 525gph filter.
• CF-500 is another compatible filter model.

What comes in the nine-pad set?

The set contains nine bio sponge pads, with three pads in each of the coarse, medium, and fine densities. This selection gives you three sponge grades for mechanical and biological filtration within a compatible canister filter.

• Coarse pads are blue.
• Medium pads are green; fine pads are black.

The pads are designed to trap most visible debris without restricting water flow. Rinse them when they become dirty to clean and reuse them.

How often should I rinse or replace the sponges?

Rinse an AQUANEAT sponge pad whenever it becomes dirty, typically about once every 1 to 4 weeks. With use, tiny debris gradually clogs the sponge’s micro holes, so replace the pads after 6 to 12 months of use or when they become worn out.

• Rinsing frequency depends on when the sponge becomes dirty.
• Replacement timing is 6 to 12 months of use, or sooner if a sponge is worn out.

AQUANEAT replacement pads suit aquarium owners whose canister filter matches one of the listed models and who want reusable sponge media in three densities. The set provides nine pads for mechanical and biological filtration in compatible aquarium canister filters.
