Yeah I knew that would get your attention. It's just I have oodles of taxidermists that want them and I can't get them, so -- being the capitalist I am...
BTW the agitator you sent me is the best one I have out of the three I have with the other two much newer. The other ones gum up and need to be cleaned before I used them each time. It causes them not to start up. Not so with the one you sent me. At this moment it's being used at one of two high schools I set up with systems and fish. It's being used to provide oxygen while a holding tank with bluegill goes up in temperature before the fish are added to system. (Acclimating water temps.)
