I have 2 emperor 400 filters on my 150g and they recently became very noisy. I turned them off and tried to see what the problem was so I took them apart and couldn't figure out why. When I put them back together, the filters wouldn't turn back on so I took the tubes out and the propellers weren't turning. I have to kind of push them with my finger to get them to start turning them and this happens whenever I turn them off to do my water change. Does anyone know how I can fix these or do I just have to buy 2 new filters?
Also, has anyone had problems with the biowheel not turning after a few months? The wheels on mine stopped turning and I don't know how to get them to start again cuz I hear you're not supposed to rinse them off.
