Premium Aquarium Biochemical Sponge Filter by QANVEE

High-density porous sponge structure ensures superior mechanical and biological filtration, trapping debris while fostering beneficial bacteria growth.

Reinforced ABS plastic frame with precision-molded seams for durability, resisting warping even under continuous submersion.

Dual-layer sponge design (30PPI coarse outer layer + 45PPI fine inner layer) maximizes particle capture efficiency without clogging.

Integrated lift tube creates optimal water circulation, oxygenating tanks up to 40 gallons (150L) for freshwater/shrimp/hatchery setups.

Silent operation with adjustable airflow valve, compatible with air pumps under 5W – ideal for bedroom aquariums or office nano tanks.

Pre-drilled slots allow effortless media customization (activated carbon/ceramic rings) to target ammonia spikes or medication removal.

FDA-grade materials ensure 100% non-toxic performance, safer than plastic mesh filters for delicate species like bettas or dwarf shrimp.

Includes suction cups with anti-slip grooves for secure mounting on glass or acrylic walls up to 12mm thick.

Maintenance-friendly design – squeeze-cleaning takes under 30 seconds with no disassembly required.
