Had this pump for a while and finally got it installed on my 400 gallon and my wife says it's too loud for the living room (has a definite hum). It has 2 days of use on it (freshwater) and growing. Going to try a submersible DC pump instead for that dead quiet aquarium.
Has both impellers and a new seal (barracuda impeller installed, easy to swap though). Located in Orting, WA. $275 OBO.
I can get photos but it is literally exactly like you imagine it would look.
