Double Head Aquarium Oxygen Filtration Pump With Bio Sponge

Meet the Double Head Aquarium Oxygen Filtration Pump With Bio Sponge — a compact, high-efficiency filtration solution designed to keep your fish tank pristine. Built for reliability, it blends mechanical filtration, biological filtration, and oxygenation in one versatile unit, so your aquatic friends enjoy cleaner water and better health.

Key Features

• Sponge Filter: Environmentally friendly high-density sponge element absorbs dirt, quickly decomposes fish feces, and eliminates odors for a fresher aquarium.
• Oxygen Cycle & Filtration: Works with an air pump to boost dissolved oxygen while enabling biological filtration. Aerobic bacteria colonize the sponge, aiding nitrogen cycling and water clarity.
• Water Cleaning: The sponge captures larger waste particles to mechanically clean water without trapping juvenile fish.
• Multipurpose Design: Functions as a primary or secondary filter, making it ideal for growth stages or additional filtration capacity.
• Easy to Install: Can be used as a pre-filter unit on external or top filters, simplifying setup and maintenance.
