The Poth-O-Carry™ Versa max is the bigger brother of the Versa. As you can see
in the photos, it comfortably eats two Versa baskets for breakfast. Measuring
in at just shy of 8" x 4" x 4", the Versa Max can take nearly anything you can
throw at it. Not only is the Versa Max a dual-rail design, but it's connectors
on the back are doubled up as well, providing superior stability, at the
expense of some vertical movement (the max basket lip can travel from 1" above
the aquarium rim, to 3" below, giving the bottom of the basket access to water
nearly 7" below the rim). Like the Versa, the Versa Max has breathing and root
holes on the left and right sides, as well as the bottom.
Standard Rim will support up to 1.5" rims, and the Rimless Option will work
for rimless tanks up to .5" in thickness.
The photos show you the height variability. :D I hope you like it!
