You'll appreciate the versatility and durability of these 40 gallon acrylic tanks. They allow you to safely create a freshwater, marine or reef environment. And while acrylic tanks weigh less than half of their glass counterparts, they are also 17 times stronger, as well as more flexible, making them virtually break resistant. Since acrylic is impervious to the corrosive effects of saltwater, SeaClear acrylic aquariums are suitable for both fresh or saltwater use. SeaClear acrylic aquariums, manufactured by CASCO Group, Inc, carry the limited lifetime warranty against leakage.
