I went out to get quotes for my big viv. And no, bshmerlie, I won't enter contest, as this will take me all summer! I found that glass and acrylic are similar in price, acrylic probably easier for a door, as they make acrylic hinges. But they advised me about not using bleach or vinager on acrylic for cleaning. So it worries me on it's durability. The other concern is they said it can't be in sunlight as this will cause it to fog over time, wouldn't grow lights have the same effect? How many of u have acrylic vivs? And have u heard of any problems? the total will be about 90 gal, 24x24x36. Or 110 24x24x48 for cutting purposes, as I will be charged for waste
