I clean the blue pad's in my Eheim's under the tap with no problem's.
Never touch the bio-media (substrat pro), except to back flush with the water from the canister after I fetch all the baby shrimp's from it.
Much larger surface area for bacteria to colonize on substrate,wood,rock, and plant leaves in my view,so I do not worry bout losing some from cleaning the pad's under the tap.
