I was at my local megamart (Meijer) tonight and they had 29 gallon Tetra Aquariums for $34. I inspected the inside a bit and found that the silicone along the edges was a little inconsistent. The bottom seams seemed to have a ton while some of the vertical seams had only a a little at the very deepest edge of the joint, not the heavy coverage I usually see. Should I have concern buying one of these or is that pretty typical?
