Our 1 gallon aquarium utilizes new, UV treated polymers to create thick, sturdy-walled aquariums that are clearer than glass yet tough enough to take on a brick, literally. The aquarium body is made from sturdy 3/16” shatter proof PolyCrystal - which unlike glass, also acts as an insulator to help keep your water temperatures stable for your fish. PolyCrystal is a new formulation of top-quality, food grade polycarbonate polymer that is commonly used in the restaurant industry to mimic fancy, crystal barware that looks stunning and will not break, with an extra thick base. With almost 15 years since our very first order, we see the difference and so will you.
