I just installed an eheim 2213 on my tank. Its my first canister filter and I'm pretty sure i set it up right. My only question is I thought the filter media inside was supposed go move around when the water flows thru. It came pre packed. I didnt need to put any media in. The water is definitely flowing, but the balls inside aren't moving. Is that okay?
