Features

  • Multi-functional Sponge Filter: Provides oxygenation, physical filtration and biological filtration all in one, ensuring clean and clear water for your small fish or shrimp.
  • Small and Compact Design: Take up minimal space in the tank, allowing for extra room for your fish to swim and easy to set up just by connecting to an air pump with an airline (note: air pump and air tube not included)
  • Ultra-quiet submersible filter and aeration pump: Run on air-drive, ultra-quiet and come with a small air stone for aeration. Notice: choose a powerful air pump suitable for the size of your tank and remember to push the diffuser into the small hole inside the filter.
  • Wide applicability: suitable for 2-15 gallon small fish tanks, including breeding fry tanks, shrimp tanks, betta tanks, breeder tanks, snail tanks, small turtle tanks, goldfish tanks, and other shallow water tanks.
  • Replaceable Sponges and Filter Media: Easily removable for cleaning or replacement, with the option to switch them out with different types of filter media.

  • Perfect for the breeding tank
Size: Small - fit for 2-15 gallon tanks
Low flow and lots of aeration. Setup was as easy as plugging in the air tube and putting it in the tank. Helps to keep my breeder tank clean without the high water flow of a traditional filter that would stress out my fish fry.

  • Excellent, very silent and effective
Size: Small - fit for 2-15 gallon tanks
The larger version of this product looks exactly the same. Be sure to check dimensions carefully so you don’t get tricked into getting the bigger (4”) version.

  • Keeps fish entertained
Size: Small - fit for 2-15 gallon tanks
I notice my fish loves to swim past the bubbles so I guess it keeps him entertained. Looks nice and it’s suppose to help with the cycle environment.
