Intake Pre-Filter Sponge


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.


Small: 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.
