Splash acrylic block panels from Allplastics Engineering are made from a specially developed acrylic grade that is highly weather resistant. This acrylic has excellent clarity, optical properties, mechanical properties and rigidity. It is simple to fabricate (cut, bend and polish) to enhance the cosmetic appearances of aquariums or pool surrounds. It is also simple to clean: light surface marks on Splash can be polished, and marks can be removed. selector.com/products/acrylic-pool-and-aquarium-windows-and-walls-splash-2
