I won this pump at an aquarium show a month or so ago. I was planning to use it on my innovative marine 30. When I opened it and got everything out I tried to put it in the back of the tank. It didn’t fit by millimeters. So I just packaged everything up again and put it back in the box. It retails for $350 online. I’m willing to do $300 and free shipping. Or if you have any offers let me know. You can text me any questions at 84329077 three nine.
