Review on Peristaltic Variable 100 240V Aquarium Analytic by Myron Brooks

I can't find a price for these pumps yet. I use this pump to balance the PH in my feed tank when connected to a Milwaukee controller. In my opinion the pump motor is upside down because the housing is hanging on 2 screws. I took it apart and rotated the motor so the tubes were facing down because they were facing up which caused the tubes to buckle when hanging. Very easy to fix. Otherwise everything seems fine. Looks like the engines will be interchangeable if he dies.
