What does that mean? Simply this: We stand behind our product 100 percent. Our continuing goal is to manufacture the finest acrylic aquariums and systems available. We support that quality with value and service. We feel that acrylic makes a better aquarium. Acrylic aquariums are brighter, lighter and stronger than glass tanks. Each ClearforLife 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 AAT product a superior choice. How do we compare? We offer the highest quality at truly competitive prices. We provide tanks that are easy to set up, easy to maintain, and that offer long life. Best of all, we price our products to guarantee our customers receive top value.
