Dual Bio Sponge Filter for Betta Fry Aquarium (4-Pack)

Our AQUAPAPA sponge filters are a cost-effective and easy-to-use aquarium filtration solution, designed to keep your tank water clear and your fish healthy. These versatile filters can be used for both freshwater and saltwater tanks, providing both mechanical and biological filtration.

The AQUAPAPA Sponge Filter is well-suited for aquariums ranging from 15 to 30 gallons. It functions by using an external air pump or an integral water pump to draw water through the sponge walls. As the air pump pushes air into the hollow cavity of the sponge filter, bubbles rise from the top lift tube, creating a gentle water flow that pulls water through the sponge. This process provides efficient mechanical and biological filtration for your tank.

Maintaining the AQUAPAPA Sponge Filter is a breeze. Simply scoop out some old tank water, wash the sponge in the water, and squeeze out any buildup until it's clean. This should be done approximately once a month. It's also recommended to change 25-30% of the water weekly to keep your tank healthy.

Key features of the AQUAPAPA Sponge Filter include:

• Provides both mechanical and biological filtration for your tank
• Suitable for use in freshwater and saltwater tanks
• Easy to set up - just connect to an air pump (sold separately) for aeration and filtration
• Traps waste particles and improves water clarity
• Filters water without trapping small fish

The package includes 4 sponge filters, each capable of handling a tank up to 30 gallons. The air infusion chamber within the filter produces numerous tiny bubbles, which promote gas exchange and increase the dissolved oxygen levels in the water, making it great for tanks ranging from 15 to 30 gallons.

Constructed with double sponges, each filter measures 5.8 inches wide and 6.25 inches high (with the telescopic tube extended to 9 inches). The filter is 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.

Customers have provided overwhelmingly positive feedback on the AQUAPAPA Sponge Filter, with an average rating of 4.6 out of 5 stars across 369 reviews. Reviewers have praised the filter's effectiveness, ease of use, and value for money.

Whether you're looking to set up a new tank or improve the filtration in your existing one, the AQUAPAPA Sponge Filter is a reliable and affordable solution to keep your aquarium water clean and your fish thriving.
