DOUBLE WATER OUTLET - This filter is innovatively designed with dual water outlets to ensure more even water distribution in your fish tank!
  • KIND REMINDER – If your tank is very large, choose 2 filters! Place a filter at both the left and right corners at the back side. You will get full filtration and great water circulation in your tank!

My aquarium sits in a room with lots of natural light and I couldn’t seem to knock the last bit of cloudiness from my water and I wanted to avoid more additives. I decided to try this filter in addition to a powerhead, sponge filter and UV light filteration that I already had set up in the aquarium. It finally did the trick. It took a few days to cycle through but now the water is crystal clear. It’s a good, sturdy, powerful filter. I can’t speak yet to the longevity of it’s durability but so far so good!

Wish I would have bought months ago!!This filter is great. It’s a little larger than most filters. Have a 10 gallon tank. This filter is a beast in the tank! About average as far as sound.

It's small! It's strong! It's quiet! It's thorough! It's in my 90 gallon, on one end, and pushes the water in a full circle. The current isn't overly strong, either! My fish love it and are brighter colored.

It killed my fish! Large goldfish! It was perfectly healthy and we decided to try a new filter. Our 9 year goldfish survived everything but a day with this filter. Mom is devastated.
