The best option is acrylic...

The material of choice for many who prefer its aesthetics and many of its installation advantages. Acrylic components usually point out that the best can be said of glass systems is that they are initially less expensive. But glass tanks do not retain their value. This is not the case with acrylic. I’ve seen many acrylic tanks sell for more than their original after years of use

Why do acrylic aquariums hold their value relative to glass? They are stronger, resist breaks and leakage, offer better thermal insulation (especially important with systems that are consistently kept warmer or colder than room temperature), and are clearer, lighter and simpler to move.

No one will argue with the fact that acrylic is much easier to handle and modify for filtration and water circulation fittings by drilling or cutting. No hobbyist would attempt to drill filtration-fitting holes in a large, expensive glass tank – special tools and glass working experience is required for that job. (Professionals usually drill the glass before assembling the tank.) On the other hand, a hobbyist and friend can easily maneuver an acrylic aquarium, and drilling is easily within the skill range of any handy person.

While both glass and acrylic can be scratched, with acrylic you can remove such scratches. The same cannot be said of glass.

Acrylic tanks are molded, cast, and fabricated into some amazingly beautiful shapes. A functional acrylic system that is a breeze to maintain and a sight to behold for 20-plus years is a better investment, to my mind, than a glass system that is much more susceptible to leakage and breakage.

For ease of setup and maintenance, prevention of evaporation, and retention of long-term value, acrylic tanks are hard to beat for marine use.
