An overflow box is a great way to keep the water level at a constant in your saltwater aquarium as well as increase the rate at which surface water, and the film and dust with it, is removed.

  • Good, solid product By Eric on 1/11/2015

    Got this for my 35 gallon cube. It is built soundly and feels solid. It works well, however, I wish some of the teeth were cut slightly bigger to allow more to flow through.
