The pre-filter or intake sponge is a simple foam cylinder that is designed to slip over the intake tube of hang-on-back (HOB) and canister filters. The filter intake tube often has large openings that allow sizable objects to get sucked up by the filter, potentially ruining the motor, so use a pre-filter sponge to help prevent baby fish, dwarf shrimp, little snails, plant leaves, fish food, and other debris from entering the filter.

Sponge filters offer reliability and hassle-free operation. With no moving parts, all you need is an air pump with some airline tubing, and you've got a filter that is fully contained within your aquarium. Sponge filters are completely reusable, don't need any replacement cartridges, and last for several years. Plus, they are gentle enough for betta fish, baby fry, shrimp, and other slow-moving species.
