Quickly Remove Green Problems: We have integrated a more powerful light that will help you solve the green water problem within 1-3 days, especially suitable for 20/30/40/55/75 gallon aquariums. This is really amazing!
Expensive Pure Copper Durable Motor: Our motor has been rigorously tested for extended dry-run conditions, to ensure it can withstand overheating without damage. By utilizing a pure copper motor and optimizing the cross-sectional area of the copper wire, we have significantly reduced the operating temperature. This means the motor can now run continuously for extended periods without the risk of damage, ensuring your fish remain vibrant.
No More Water Leaks!!! If you abandon the canister filter on the floor or space-consuming hang-on-back filters, you will find that this internal filter is perfect for indoor use. The filter has a built-in sponge, which gives our filter performance comparable to any other filter. At the same time, you no longer have to worry about water leaking out or even causing significant damage.
