Looks like my most excellent and cool koi "SKULL" has died due to injuries suffered in the mink attack. Poor guy didn't look that great the past two weeks, and it was all he could to do manage a noble exit.
I have a new pump and it's working well. Bought from a local Agway for a small fortune, but I like spending money with a local business and this until I can get a warranty replacement from the store,
rather than have to ship to some address...who won't even return my email 
So when is somebody else going to build a pond? I've learned so much I want to share
