Efficient Green Water Treatment: Designed for targeting green water, this fish tank filter features a built-in 8W U - V light and a maximum flow rate of 200 GPH, suitable for aquariums ranging from 20 to 120 gallons. U - V for aquarium effectively clears green water within 3 to 7 days, providing crystal-clear and healthy aquarium water. The U - V light comes with an external controller, allowing operating times of 0, 4, 8, 12, or 24 hours per day. Whether for efficient cleaning or regular maintenance, it meets all your needs.

Unique Ammonia-Reducing Media: The final filtration step includes a unique ammonia-reducing media, designed to help reduce excess ammonia. Its fine, porous structure increases contact surface area with the water, effectively promoting a healthier aquatic environment for both fish and plants.

Multi-Stage Filtration: Stage 1: Coarse bio-sponge filters out particles and debris. Stage 2: Fine bio-sponge provides additional filtration while offering space and habitat for beneficial microbes, which help to break down ammonia and nitrites from fish waste. Stage 3: Ammonia-reducing media further purifies the water, effectively neutralizing excess ammonia and ensuring a healthy water cycle.

Flexible Water Output Options: 1. Aerated Output: Water is mixed with air through a connected tube, releasing oxygenated flow and creating bubbles for aeration. 2. Spray Bar Output: Water flows through a spray bar with multiple holes, introducing oxygen and agitating the water surface. 3. Submerged Jet Outlet: Creates an underwater circulation, enhancing water flow and filtration.

6-in-1 Fish Filter for Aquariums: This aquarium filter combines six essential functions: filtration, U - V, water circulation, air flow, rain shower, and ammonia reduction. Easy to install, user-friendly, and designed for simplicity, it’s perfect for anyone to operate with ease.

Quiet, Aesthetic, and Safe: Please note that this submersible aquarium filter is designed to operate fully submerged underwater. Running the unit above the water level may increase noise and potentially cause damage. When properly submerged, the internal aquarium filter operates quietly, ensuring no disturbance to living areas. The classic black cylindrical design blends seamlessly with the aquarium, without drawing attention away from the fish. The entire unit has undergone multiple safety tests, providing efficient filtration while ensuring safety and durability.
