Urgent Acrylic Warp - How Much Is Acceptable???

Hello,
Started filling my 110 acrylic today and it is currently half filled and is warping; it is bowing out a good 1/2 inch and is only half filled!! Just how much is acceptable AND safe? I'm not filling anymore water until I know this thing will not burst! It is a 6 sided tank 61" long, 24" tall
Thanks!

 

Fill it outside with freshwater first so you can see the effects of warping at full. That way u dont waste saltwater, have water carpets, etc.

 

The fellow reefer I bought it from had it up and running days before I bought it, so I assumed all would be good... and did not water test it before bring it inside. It is in a bedroom almost half filled with RODI and 60# sand, no salt yet. I assume the bow will only get worse and wanting any feed back of anyone else that has a bowed acrylic before I go any further.
This will be a lesson learned either way - don't trust anyone's word when they are getting your money and ALWAYS do a fill test outside first!

 

Is there a brace on the top?

 

This is the question of the day. If there isnt a brace I would be very worried.

 

The top is well braced in comparison to other acrylic tanks I've seen.

 

Oh wow,


No idea what you payed for it, but with that much water on a used tank with that much of a bow I would feel uncomfortable.

Hope it ends well for you, I myself would be looking for a refund and return of the tank. Uncomfortable for those involved but hey you forked out the money and you have the potential for a huge loss once it's filled with rock and live stock. The integrity of the tank seems compromised to me. JM2C.

Good Luck

 

How thick is that?

 

Top brace is also 3/8"
