haha yeah I said 6ft high. It would be 5.5 deep actually. I included the 6 inch floor. But I planned on just two pieces of either glass or acrylic in the front. There will be 6 inches of concrete surrounding all sides except the center where it will be 1 ft think. Nothing is really set in stone right now, but this is what I plan so far. Just trying to cover everything first to make sure i get the correct measurements on everything and get the right glass so it does explode shortly after filling the tank up. So I'm up for any suggestions, this will be my first tank build and I'd rather be safe than sorry.
