SunGrow Betta Fish & Turtle Sponge Small Aquarium Tank Water System Filter

• Crafted to make taking care of your finned friends easier for you.
• Design is made for neon tetra, betta, fry and other small fish.
• Produces little bubbles, which help form a current, add to oxygen levels, and encourage breeding and spawning—and the sponge filter is perfect for providing extra food.
• Just connect an air pump and airline tubing (sold separately) to the filter and put it in your tank!
• If it gets dirty, simply use water from your tank to clean this filter and rinse until the water is clear.

Replace this cotton every 5 to 6 months to ensure proper filtration. You may buy 3-pack replacement sponge pack (sold separately) along with this product.

• Insert the plastic tube in the airline tubing (sold separately).
• Insert one end of the airline tubing into the sponge filter.
• Insert the other end of the airline tubing to the air pump. Now your device is ready to work.
