## 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 1 to 5 gallons. Note: Do not use this filter in tanks that are too small, as it may stress the fish. The filter may stop working due to improper installation or insufficient water volume. If the problem cannot be solved, please contact customer service for assistance.
- 🐟 AFTER SALES SERVICE - We offer 365-day support. If you encounter any issues with your filter, contact us immediately. Enjoy worry-free returns, quick responses, quality assurance, expert advice, and a comprehensive warranty. Our customer service team is always ready to assist and resolve any issues you may have.
