Foam Inlet Strainer Pre Filter for Aquarium Fish Tank Filters Canister External Coarse 25ppi or Fine 40ppi (2 Pack Coarse 25ppi)

Pack of 2 intake pre filter foams ideal for use with external canister filter inlets. Each foam measures 120mm long, 60mm total diameter and internal hole 15mm diameter. The foams are sealed on one end and open on the other. The hole can be widened for larger intake tubes if required. We recommend removing the existing plastic strainer on the filter inlet and pushing the pre filter foam over the pipe. We have these foams available in two different foam grades. Coarse (25ppi) and Fine (40ppi). Please select the grade required from the drop down menu when ordering. The coarse 25ppi foams are ideal for general use, and the 40ppi are ideal for tanks with very small fish such as fry or shrimp aquariums.
