Our 3-in-1 Filter Cartridge offers efficient filtration with a unique waterfall design that oxygenates the water to promote healthier, more active fish while reducing splashing for a quiet return. The adjustable flow allows you to reduce the flow for delicate fish, shrimp, plants, or other low-flow needs without compromising filtration efficiency.

To ensure the filter is working properly, you should check if the flow is too strong for your fish. Delicate fish, such as bettas and goldfish, require a more gentle water flow, as they may show signs of stress if the flow is too strong.

The no-mess filter cartridge changes the biological, mechanical, and chemical filtration in one fully assembled and ready-to-use unit. It can be easily slid out for quick maintenance, and you can customize it to fit your specific needs. The pre-filter sponge prevents small fish, shrimp, and debris from getting sucked up, while also purifying the waste chemicals in the water and adding more mechanical filtration.

The leveling knob is used to ensure the water level in the filter is not at such an extreme angle as to cause spillage. The patent-pending priming system allows the filter to auto-restart if power is interrupted and restored.

If your filter stops working, check if the impeller is clogged. Use tweezers to gently remove the impeller, rinse it, clean the impeller chamber, and then gently put the impeller back into place, making sure it's free to rotate and prime the filter.

Our slim filter is designed for both external and internal installation, with dimensions ranging from 4.5 x 3.5 x 2.9 inches to 5.3 x 1.6 x 1.2 inches. The max output ranges from 40 GPH to 53 GPH, and the power consumption is between 3W and 5W, making it suitable for aquariums up to 10 gallons.

The filter tube is extendable, and it's recommended to fill the filter case completely with water before use. If the filter doesn't start or makes a mechanical noise, try turning the impeller by hand and rinsing the impeller and filter to remove any blockages. The filter will automatically restart after a power outage.

While this filter is not recommended for turtle tanks, it can be used in framed aquariums, as the width between the intake tube and housing is 0.5 inches, making it a great choice for nano and pico tanks up to 5 gallons.
