Cylindrical sponges cover the inflow holes of filter pipes to prevent tiny animals from getting sucked in and trap particles and debris. They also function as small bio filters. Sm all: 1 cm inner diameter, 2" length Medium: 1.5 cm inner diameter, 2.75" length Large: 2 cm inner diameter, 3" length The sponges stretch so they should work for pipes that are +/- 5mm from the inner diameter of the sponge.
