Dimension: 8x4.5cm/3.2" x1.8", the inside hole diameter is 2cm/0.8"; for a snug fit, check the size you need carefully before placing an order. The sponge's inner diameter accommodates filter intake within 0.69-1.15 inches (17.7–29.2 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 reed 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; jt unpack and rinse them and these sponge filters will puff up to normal shape and size.)
