if a person were considering a 10 foot tank, should he get glass or acrylic? With a big tank like that, what's the pro's and con's? Would glass be cheaper? Would Acrylic be less likely to bust? Does scratching matter with Freshwater tanks--won't be scraping any marine crusty rock stuff off the glass. Weight doesn't matter since a tank that big will be on the ground floor anyway. What about thickness of material. I saw a big marine tank, and the acrylic was so thick, you could really only see what is directly in front of the eye. Look through the acrylic at the slightest angle, and the thickness of the material distorted light too much to see what's in the tank. That happen with glass?
