I have a 29 gallon tank with a AC50 which has been set up for about five months. The setup and filter were new. I went out of town and when I got back the filter was humming but not working. I took it all apart and couldn't find anything that would make it stop working. I replaced the motor unit and it worked but now that unit is humming and not working.
Has anyone had a problem like this? Do I need to replace the entire unit?
