The entire bottom of the aquarium must be fully and evenly supported on a flat, level surface at all times. The use of a stand that supports the tank around the perimeter only, as often used for glass tanks, will void the warranty. An appropriate stand for acrylic tanks will be strong enough to hold the weight and will have a top that is flat enough so that if the tank were set directly on it, there would be no dips or humps that would cause the tank bottom to not make contact with the top of the stand at any point before it is filled. For all practical purposes, the top of the stand must be as strong at any given point in the middle as it is on the perimeter. This means that a sheet of plywood cannot simply be set on top of a perimeter stand, as when filled with water the tank bottom could bulge down in the middle and put extra stress on the bonds.

As we explain in our section of this web site, we strongly believe that glass is a better material for aquarium use than acrylic. However, when it comes to aquarium sump use we feel that HDPE is better than both acrylic and glass.

Only then did Mr Shikiyama find that America levied a 36% import tax on acrylic-resin board. His pleas for help to Japan's then Ministry of International Trade and Industry met with indifference. In despair, he went to the American embassy in Tokyo, and thence to America's Commerce Department. He flew to Washington, , where he was advised to import the acrylic glass as a product (which he named AquaWall) not as a material, as the tax would drop to 2%, saving Monterey Bay Aquarium almost $1m. He was praised fulsomely at the aquarium's opening ceremony, paving the way for fresh contracts.
Acrylic or Glass aquarium???which is better? - Michigan Reefers
I've kept various types and sizes of aquariums for years, always in glass tanks. I'm planning to upgrade my seahorse aquarium to a larger size--somewhere in the 50 or so gallon size and I've been considering using an acrylic aquarium. I do know about the scratching issues and the smaller tank top openings--what I'm wondering is, those of you who use acrylic or have used acrylic aquariums--how do you like them and would you recommend using one? How big an issue is the scratching? Are the smaller tank openings a problem? Let me know what you think.If I am planning an aquarium that will include lots of live rock, I almost always prefer a standard glass tank. It's just too difficult to wrestle large pieces of live rock through those restricted cutouts in the top of an acrylic aquarium, and way too easy to scratch the viewing surface while you're attempting to arrange the rockwork through those limited access ports.
