The statement of acrylic is easily scratched - NO from Tankmaker.com
Glass is better against scratches - NO from Tankmaker.com
What to do if scratches found? Glass unable to remove, acrylic can be removed easily - YES from Tankmaker.com
Our answer is basaed on 2 tests conducted by Tankmaker SGTeam. Acrylic material used is Plexiglas from Evonik.
With same force used on scratch test, deep cut found on surface of both glass sample while fine hairlines was found on surfaces of both acrylics sample. This shown acrylic provide more resistance to scratch than glass; which in line to the properties of acrylic material that it posses strong sustainability and anti-impulse force (16 times stronger than the glasses).
Another merit of acrylic is, the scratches can be removed easily through polish. While the scratches for glass is almost impossible to be removed for aquarium tank.
