29g reef tank with slight bow...should I be worried?
 

I just noticed that my 29g glass tank has a very slight bow. I found that in the middle the glass comes out about 2-3mm further than it is on the edges. Is this normal?

Samething happened to me with FW 29G last year. I asked and pple said: It's ok. But I didn't trust it so still empty 1/2 off and applied a middle brace on - Safe better than sorry, ehehe..

Thats a good idea. I may look into adding one depending on what others here say.

Its fine. My 20H does the same thing, and its been that way for years.
