Round Conical Bottom Nesting Tanks have all the benefits of flat-bottom tanks with the advantage of a conical bottom. A 20 degree cone-bottom forces high solids to be removed from the bottom continuously. This allows for our tanks to be self cleaning for months at a time.

* Make sure to combine the height of the tank plus the stand when measuring holding area.
The stands built by Polytank are made of heavy gauge steel and are sprayed with a white baked-on Powder Coat Paint for a durable long-lasting finish. These stands are very durable and value-priced. There is 12″ of clearance below the bottom of the cone on all conical bottom tanks in our stands.
