Glass versus Acrylic. High-quality glass aquariums generally project a more refined appearance, and can seem more elegant, than acrylic aquariums of equal dimensions. Construction techniques have advanced significantly; now bold bowfront designs and even canoe or double bowfront aquariums are available for applications where the aquarium is viewed from two or more sides. Super-high-clarity glass that shows no green or blue tinting is also available. Known as low-iron Starphire glass, this ultra-clear variety can cost twice as much as regular glass, but it offers noticeably higher clarity. Traditional beauty takes center stage with a glass aquarium by Aqua Creations. With optional Starphire glass, we can build a glass aquarium that is over 99% optically clear, in almost any shape or size. With cutting edge building techniques and hi-tech tempered glass, we're redefining the limits.
