I have been using a Krystal Clear Model 637 Pool Filter/Pump(rated 800 gph)for my Goldfish/Koi Pond. I was doing some cleaning and filter upgrades and along the way I guess a small piece of gravel got to the impeller, well standing at the plug I wasn't fast enough to save it. I have been looking over the web to find a replacement with no luck so far. Does anyone know of a place that I could check ? If the parts place is in the US that would be great. Here is a picture of the pump,If someone could ID it That would be a great help also.
