These fine filter pads from Eheim are for use with the Eheim Classic External Filter Plus 600.
The Eheim 2217 Classic includes three fine foam filter pads. They work in conjunction with the other filter media to thoroughly clean the water.
They can be rinsed out in aquarium water, but should replaced when fully dirty or after 3 washes.
