Abstract
An assembly which is used with an undergravel aquarium filter in order to keep the passage between the bottom cavity under the filter and the uptake tube free from blockage due to gravel. The assembly is in the form of a collar which extends from the bottom plate of the undergravel filter at the point of insertion of the uptake tube. A ring, with a structure to prevent the passage of gravel through the central portion thereof is fitted within the collar. The ring may be removed from the collar to clear gravel out from the collar before insertion of the uptake tube.
