So I was sitting here earlier and noticed that there was no current in my Pandas tank. Its a 12 gallon Eclipse system,with that biowheel set up. I did a wc on them anyways,so I took off the filter part. Took it apart,took out the impeller (looked fine,nothing stuck on it). Nothing was lodged anywhere. So I dont know why its not doing anything. I called Marineland,and he had me turn it over,with impeller in,to see if it turned. Well it did,so he said filter is fine. I was like um but its not,its not doing anything. So I have no idea what else to do. The lfs is a pain,they told me to call Marineland cause they dont do exchanges. Help??
