Product details

About this item

This is a hanging filter that adheres to the aquarium wall. It uses environmentally friendly sponge as filter material and works in conjunction with an air pump to achieve dual functions of oxygenation and filtration. Note: Before use, soak the filter in aquarium water for 5 minutes to facilitate the growth of nitrifying bacteria colonies. When rinsing the sponge, use aquarium water only; do not use hot water. Features: Features a multi-layered design principle, providing maximum surface area without obstructing water flow. They are easy to clean and operate silently without any noise when in use. Air stones generate a large number of bubbles, increasing the oxygen dissolution in the water. Made of bio-sponge, it is more durable. The design of bio-sponge filters is based on extensive testing. They are particularly suitable for small freshwater fish like guppies and bettas.
