Aquarium Bio Sponge Filter for Fry, Betta, Shrimp Fish Tank up to 55 Gal

The AQUAPAPA sponge filters are a cost-effective and easy-to-use aquarium filter that help keep tank water clear and your tank healthy. These sponge filters are designed for aquariums ranging from 20 to 55 gallons.

The sponge filter functions by using an external air pump or an integral water pump to push air into the hollow cavity inside the sponge filter through the tubing. This creates bubbles that rise from the top lift tube, drawing water through the sponge walls. This process provides both mechanical and biological filtration for your tank.

Maintenance is simple - just scoop out some old tank water, wash the sponge in the water, and squeeze out the buildup until it's clean. The sponge should be cleaned every month, and it's recommended to change out 25-30% of the water weekly.

Key features of the AQUAPAPA sponge filters include: - Provides mechanical and biological filtration for both freshwater and saltwater tanks - Easy to set up - just connect to an air pump to provide aeration and filtration - Traps waste particles and improves water clarity - Filters water without trapping small fish

The air infusion chamber produces numerous minute bubbles, which promotes the gas exchange process and increases the dissolved oxygen level in the water. The filter is designed for tanks up to 55 gallons, with each sponge filter measuring 6.5 inches wide and 9.4 inches high (telescopic lift tube extended to 13.8 inches high).

The sponge filter is constructed with double sponges and is attached to the tank glass by two suction cups. All parts can be detached for cleaning or replacement, and it's recommended to wash the sponge foam with tank water instead of tap water.

The AQUAPAPA sponge filters are available in various sizes to accommodate different tank capacities, ranging from 5-10 gallons to 60-100 gallons. They have received positive customer reviews, with an average rating of 4.6 out of 5 stars.

In summary, the AQUAPAPA sponge filters are a cost-effective and efficient solution for maintaining the water quality and health of your aquarium, providing both mechanical and biological filtration through a simple and easy-to-use design.
