Custom Acrylic Tanks

Our tanks range from 125 gallons to thousands of gallons. All tanks are made of high quality commercial grade acrylic. Material thickness increases with size and height of the aquarium-up to 3″ for taller displays. All tanks have minimum 3/4″ tops that allows larger top openings for access.
