Aquarium Bio Sponge Filter for Fry, Betta, Shrimp - Up to 55 Gal

The AQUAPAPA sponge filters are a cost-effective and easy-to-use aquarium filtering solution, designed to keep your tank's water clear and your aquatic life healthy. These efficient sponge filters provide both mechanical and biological filtration for aquariums ranging from 20 to 55 gallons.

The sponge filter functions by utilizing an external air pump or an integral water pump. The air pump pushes air into the hollow cavity inside the sponge filter through the tubing, and the bubbles rise from the top lift tube, drawing water through the sponge walls. This process not only provides mechanical filtration by trapping waste particles but also facilitates the biological filtration process, improving the overall water quality.

Maintaining the AQUAPAPA sponge filters is a straightforward task. Simply scoop out some old tank water into a bucket, wash the sponge in the water, and squeeze out the buildup until it's clean. This cleaning process should be carried out monthly. It is also recommended to change 25-30% of the water weekly to ensure optimal tank conditions.

The key features of these sponge filters include:

• Providing both mechanical and biological filtration for freshwater and saltwater tanks
• Easy setup - just connect to an air pump and it's ready to provide aeration and filtration
• Trapping waste particles and improving water clarity
• Filtering water without trapping small fish

The package includes two sponge filters, each suitable for tanks up to 55 gallons. The air infusion chamber produces numerous minute bubbles, promoting gas exchange and increasing the dissolved oxygen level in the water, making them great for tanks ranging from 20 to 55 gallons.

Constructed with double sponges, each filter measures 6.5 inches wide and 9.4 inches high (with the telescopic lift tube extended to 13.8 inches). The filters are designed to attach to the tank glass using two suction cups, and all parts can be easily detached for cleaning or replacement. When cleaning the sponge, it's important to use tank water instead of tap water to preserve the beneficial bacteria.
