We feel that acrylic makes a better aquarium. Acrylic aquariums are brighter, lighter and stronger than glass tanks. Each Clear-forLife™ aquarium is handmade using top grade materials, precision manufacturing processes, and the latest technological advances. Each seam is actually a chemical bond that "welds" the pieces together there are no bubbles so there are no leaks. Attention to detail, such as rounded safety corners, make each Clear-forLife™ product a superior choice.
