Donny is correct. It is the pump that I got when I bought his system. I plumbed the system a little differently and didn't end up using the pump. I wanted to keep it for a while to make sure that my plumbing set up worked, but now I am comfortable with it. Here are some pictures. It has had only limited use since February and is in great condition. Donny, thank you for providing that info. I will have to send you some pics of the tank. All of the occupants are still doing great.
