Anyone have issues with the seio powerheads. These piece of crap powerheads stop working every week or so. Yes I clean them with vinegar so it is not calcium or fish crap. I hate these dam powerheads can wait until I move into my house and setup my tunze's in my new tank, but being it is several months away I need a solution for now and the tunze would look really stupid in a 65 gallon. Anyone else having issues with them but what can i expect buying a pump made by Rio. Anyone have any other suggestions on powerheads. Please let me know and I will give them a try.
