So Im getting ready to purchase a 8ft x 2ft x 3ft glass aquarium or about $800, my LFS said they can build me a seamless acrylic for about 200 to 300 more depending on what I want, if I want spray bars and over flows and tops off.. I dont need spray bars, because its for my Clown Knife.. But I have heard that glass gives a really bad distortion.. Which would you guys go with? I looked at the glass tank and it didnt look like there was much distortion.. But it didnt have water in it..
