Diy Fish Tank Stand 55 Gallon. 1 gallon of water 8.34lbs times the specific gravity of say 1.025 equals 8.5485lbs (8.43 x 1.025 = 8.5485) the weight of the water will increase directly proportionate to the weight of the salt being dissolved in the water. When fish are put into an aquarium, waste can quickly reach toxic concentrations in the enclosed environment unless the tank is cycled to remove waste.
