Abstract
An aquarium filter is disclosed that provides an overflow window for indicating a blocked filter cartridge. The filter cartridge extends across the full width of the filter box and includes an overflow weir, or lip. The overflow weir forms part of the filter structure and controls the flow of water when the filter cartridge is blocked. Since the filter cartridge extends across the width of the filter box, the size of the filter for a given flow rate is reduced. The filter provides the feature of overflow indication in a more compact and efficient structure than otherwise possible.
