Key features

• •【WORLD'S SMALLEST BUT POWERFUL TRIPLE FILTRATION SYSTEMW】The Wonderfactory G1 is the world's first compact hang-on fish tank filter with triple filtration: biochemical, mechanical, and surface oil removal. Equipped with our proprietary ultra-quiet and powerful water pump, it's perfect for oxygenating, filtering, and microbial growth in small fish tanks.
• •【SUPERIOR FILTRATION MEDIA】We use high-density, medium-pore (25 PPI) polyurethane sponges and high-porosity (over 75%) ceramic balls. This combination ensures a high flow rate while effectively removing impurities, harmful chemicals, and debris, keeping your aquarium water crystal clear. The top inlet features a surface skimmer to remove oil film and floating debris.
• •【ULTRA-QUIET MOTOR】Our unique high-speed brushless motor is both powerful and energy-efficient, filtering up to 80 gallons per hour (GPH) with noise levels ≤30 dB. It delivers strong performance with minimal noise, ensuring a longer lifespan.
• •【ADJUSTABLE WATER FLOW】Easily adjust the water flow to your preference by turning the dial. The unique waterfall design promotes oxygen exchange, helping your aquatic life stay healthy and active.
• •【ENHANCED SAFETY FEATURES】The back-hanging design keeps the motor outside the tank, reducing risks of electric shock or exposure. The G1 also features a specialized intake sponge to prevent small fish and shrimp from being sucked into the filter, enhancing safety for all tank inhabitants, especially smaller or more delicate species.
• •【USAGE GUIDELINES】The Wonderfactory G1 is ideal for aquariums ranging from 3 to 15 gallons. Note: Do not use this filter in tanks that are too small, as it may stress the fish.
