Overflow Boxes


    Aquarium overflow boxes have come a long way since the mid 80s when they first became mainstream in fish keeping.  Mostly used for saltwater aquariums they are made to skim the water surface, removing many toxins that float on top of the aquarium.  The overflow boxes here mount to the aquarium after drilling holes in the aquarium wall panel.  Slim, sleek and compact, these bolt on overflow boxes have become very popular in saltwater aquariums.
