Dimension: 7x4cm/2.8" x1.6", the inside hole diameter is 1.5cm/0.6"; for a snug fit, check the size you need carefully before placing an order. The sponge's inner diameter accommodates filter intake within 0.56-0.69 inches (14.5–17.7 mm) due to its elastic properties.
Lifesaver: Keeps baby fish, shrimp, and snails from getting sucked into hob filters, power heads or canister filters by simply putting a pc of this pre-filter sponge over the intake.
Improve Filtration: Does a good job in catching flake fish foods, plants and any other large particles floating in the water keeping the tank cleaner and last longer between cleanings.
Maintenance: Rinse the sponge roll periodically based on the bio load of your aquarium tank. The material holds up well to being rinsed and reused and allows great water flow.
Includes: 12 pcs of pre-filter sponge (Note: The hole doesn't go all the way through the sponge. They come flattened in a vacuum bag; just unpack and rinse them and these sponge filters will puff up to normal shape and size.)
