Frag Tanks

Why Glass Frag Tank’s Are Better Than Acrylic

Why Glass Frag Tank’s Are Better Than Acrylic

For reefers looking to set up a frag tank the second decision that needs to be made, after how large of a tank to buy, is whether to choose a tank made of glass or acrylic.  While acrylic has a  few advantages over glass in terms of weight and the ability to be molded into various shapes, for a frag tank the decision is simple,  a glass tank, such as the Reef Casa Frag Tank is always a better option.


Since frag tanks are generally on the smaller side, and almost always a simple rectangle, the two potential advantages of acrylic are negated, leaving glass as far and away the best option.  First and foremost, glass offers a far clearer viewing experience than acrylic.  Most acrylic tanks have a slight tint to them, whereas most glass tanks, and all Reef Casa tanks, are made with ultra clear glass.  Glass tanks are also far less likely to be scratched than acrylic tanks, and are much easier to clean.

Acrylic Frag Tanks are super easy to scratch


Since sand is generally not used in a frag tank it is almost impossible to accidentally scratch a glass tank.  On the other hand, acrylic tanks are much more likely to be scratched during cleaning.  Nothing distracts more from a display of vibrant coral frags than a giant scratch on the viewing surface.  Additionally,  if a frag tank is used to transport corals to and from coral shows a glass tank is far less likely to be damaged when being moved empty than an acrylic tank.

Other reasons why glass tanks make a better choice include the fact that acrylic tanks have a tendency to discolor over time and that glass is a far better insulator than acrylic, which can help to reduce heating costs.
