I currently have two tanks. A 75 and a 38. The 75 doesn't bow at all, but the 38 does.....a lot if you ask me. At the top of the tank, across the front, if I place a straight edge on the glass, it bows a good 1/4" out in the middle. Is this normal?
 
Glass aquariums, so they say, bow a little.

But the issue gives me creeps...

do you have it in a "non problem " place?
 
I would fashion a brace for the center, if I were you. Drain the tank before you place it.

I imagine maybe a piece of wood, with two smaller pieces of wood cut to go around the top frame of the aquarium screwed into place? Then secure it to the tank itself with some silicone?

No, it's not in a "No problem" area. It's in our living room.

Tank dimensions are 36" x 12" front to back x 18" high.


I would get rid of that tank.

I hear that glass bows ( have never noticed it in 37 years in the hobby ), but let other chime in....

+1 ..1/4" seems to me like a disaster if bumped or whatever it may be..i'd ditch it and get a new one:thumbsup:
 
I would build a brace for it. It shouldn't be too hard and you will see that the bowing is gone. If you don't want to drain the tank, just use a long clamp to hold the tank back in it's original position and then build the brace. If it bows when you take the clamp off then you need to build a better brace.
 
I agree, I have never had glass noticeably bow. I always considered that one of the advantages of using a proper thickness of glass, it did not bow like acrylic has a tendency to do. If I noticed any of my glass tanks bowing I would drain and brace or replace the tank ASAP.
 
yep.. bracing is the answer.. build a top brace. you can use wood, plastic, metal, glass.. but it NEEDS to be braced.

if you choose metal. any workable metal will work IF isn't not going to touch the water. if you make the brace so that it touches the water for any length of time you need to use ONLY Stainless Steel.
