ABSTRACT:
An aluminum tank buoyancy compensation system, for use with aluminum tanks having a flat bottom, a diameter and a boot attached at the flat bottom, for offsetting the inherent positive buoyancy of an empty aluminum scuba tank, comprising a weight disk having substantially the same diameter as the tank bottom. The weight disk is inserted into the boot, and the boot is replaced onto the bottom of the tank. The weight disk is trapped between the boot and tank bottom, ballasting the tank sufficiently to compensate for the positive buoyancy of the aluminum tank.
