Keep your aquarium water clean, oxygenated, and biologically balanced with an efficient combination of mechanical and biological filtration.

The high-density sponge helps capture debris while providing a large surface area for beneficial bacteria to grow. The biological media supports a stable aquarium ecosystem, while the air-driven design improves water circulation and oxygenation.

Gentle water flow makes it especially suitable for shrimp tanks, nano aquariums, fry, and other small or delicate aquatic life.
