Key Features
Dual-Action Bio-Filtration: Delivers excellent mechanical filtration by pulling floating debris out of the water column, while acting as a premium biological hub for beneficial bacteria to thrive and clarify your tank.
Space-Saving Corner Profile: Features a practical, quarter-cylinder design that fits snugly into the back corners of your aquarium. This hides the filter footprint from plain sight and maximizes swimming room for your fish.
100% Livestock Safe: The air-driven, gentle suction makes it completely safe for baby shrimp, newborn fish fry, and long-finned species that would otherwise get pulled into or injured by powerful motorized filters.
Heavy Weighted Base: Engineered with a solid, weighted bottom plate that locks the filter to the base of your tank, preventing it from floating or tipping over even during heavy bubbles.
High Oxygenation & Low Stress: Increases vital surface agitation and drives ambient gas exchange without creating harsh, high-velocity currents that can exhaust and stress slow-swimming fish like Bettas or Fancy Goldfish.
Durable & Easy to Clean: The high-density, porous foam is designed to resist clogging and can be used repeatedly for long-term water management.
Target Applications
This versatile bio-filter is the ultimate choice for:
Shrimp & Invertebrate Breeding: Gives Neocaridina and Caridina species a massive, safe surface area to graze for biofilm.
Fry Rearing & Grow-Out Tanks: Perfectly sized for raising larger batches of delicate cichlid, discus, or livebearer fry.
Hospital & Quarantine Setups: Easy to seed with bacteria from a main display and deploy into an emergency tank without shocking weak or sick livestock.

Maintenance Instructions
Important Cleaning Tip: To preserve your tank’s delicate ecosystem, never rinse the sponge under a tap. The chlorine and chloramines in tap water will instantly kill your beneficial bacteria colony. Always squeeze and rinse the sponge gently inside a container filled with siphoned aquarium water during your routine water changes.
