I just threw out the 20gallon Aquaclear filter we had on one of our goldfish tanks becuase everytime we unplugged it, it refused to re-start, even after taking i apart and washing it, plugging it in and unplugging it over and over again. . . So we got a 20gallon aqueon. Aqueons seem SUPER reliable, they just don't make a large/heavy duty one. Anyone else?
