Ah, the long and heated debate. What is better for your aquarium, glass or acrylic? Well, allow us to give our opinion. We say acrylic – it’s lighter and stronger than glass, plus it can be just as clear (especially if you use plexiglass acrylic like we do). Glass has it’s benefits and we sell glass tanks too, but we’re more likely to recommend acrylic (especially for our bigger custom fish tanks).
