Hygger Aquarium Double Sponge Filter

$17.99

Multifunctional Aquarium Filter

With an air pump as the power source, this sponge aquarium filter combines bio-filtration, oxygenation, and physical filtration in one. The sponge can absorb fine particles to purify the water.

This filter also makes small water flow that is controlled by the air flow. The water flow is small and slow so that it does not impact the fish. It helps your small fish or shrimp to live a happy, healthy life.

Detachable Fine Filter Sponge

There are 2 kinds of filter material: filter cotton (sponge) and filter ceramic media. You can easily clean or replace the 2 sponges by taking them down from the filter. Note that don't use tap water to clean the sponges. Rinse or squeeze them with the aquarium water. The 2 sponges are fine 60 PPI (Pores Per Linear Inch) which means more surface area for beneficial little creatures to live on.

Replaceable Bio Filter Media Balls

The media balls provide a surface where helpful tiny creatures can live quickly. The filter package includes a small bag of ceramic media balls. 0.25 lb for small size, and 0.27 lb for medium size.

You can replace this ceramic media with other medias like carbon, ammonia absorbers, and anything that can keep your water sparkling clean. It is suggested to replace the ceramic media balls every 6 months or when the water permeability turns poor.
