Got my defective older pump (k-201) replaced by this, am very happy with it. Runs very quiet and is really quiet and powerful. Had previously only in my aquarium, the inner wall of the filter exchange but this was not a problem, I've directly from jewel worried and still free. Really good customer service of jewel. The pump also an adapter is and was a perfect fit. From me the full number of points for this pump and of course for amazon for rapid delivery, thank you. Mfg
