I've bought 3 marineland emperor 350 filters in the past few months and all of them have broke on me. It randomly happens when I would turn the filter off while doing a water change. The filters just wouldnt come back on. I thought maybe something was clogging them but i've cleaned them before and they would start back up but for some reason they randomly kick the bucket. I dont get it. Are these filters just garbage? I made the switch to a fluval (use to be aquaclear) h.o.b.
