This media basket is designed for the middle chamber in a Waterbox20g cube.
THIS IS FOR OLDER WATERBOX 20G Cubes. There was a slight dimension change in the 2nd chamber a few years back. That’s when I bought this and I never used it because I have the smaller 2nd chamber. Check the pics for the dimensions.
From InTank’s website:
Fits Waterbox Cube 20 aquarium inside chamber two, chamber is wider than 7-3/8"
