Review on 🐠 Tetra Whisper In-Tank Aquarium Filter with Air Pump - Effective Internal Filtration by Brando Carpenter

Love this filter. You may need to get creative if you don't use a hook that attaches to the top edge of the tank. Or if you do not place the filter directly on the ground because this filter will be too heavy for the suction cups, either place it on a small object so that the top of this filter is above the water level, or adjust the water level so that it stays below the top of this filter to properly use this filter. I use this filter in my turtle tank and it's amazing. I used to use a cornerstone filter setup with a $100 turtle filter that we had yet to remove from their waste and food. But now I came across a Whisper 20 on those first two filters and saw a huge change in water quality so I bought this Whisper 40i and took out the Rock and Turtle filter and the water quality was crisp and clear. I love these filters. (In order to insert the 2nd suction cup, you need to use a twisting motion instead of the included hook to slide the tab through the hole more easily.)
