1/2" thick or 1/2" bow on your 90? I'm going to finish filling it tomorrow with rodi, but decided not to take the chance as I feel it could fail down the road - got to have confidence in a tank this big, anything over 5 gallon for that matter.... I'm going tank shopping tomorrow, looking for a 150 - 180, might as well go bigger, right?! I will drain this one into 55g Rubbermaids or directly into the new tank depending what I find and where I place it in the room. As for this one, I'll resell it as a Bow Front acrylic and I wouldn't be lying ;D Actually I will cut it up and maybe make a small sump or something; always wanted to learn acrylic fab. Thanks for the help and I'll keep you posted.
