From 24" tanks to 30' round tanks, Reiff Manufacturing has molds for almost any common size used by North American fish hatcheries.
Up to and including 12' round tanks, our tanks are produced in a single piece off a male monolithic mold.
Our 20' tanks (pictured to the left and right) and only two pieces, and our large 30' tanks are produced in 3 pieces. This creates less seams than a panel tank, and installation is far simpler and cheaper. You end up with a higher quality tank.
