I am looking into getting a tank that is 7-8ft long and up to 30in tall and just want to confirm how to determine the thickness of acrylic required. I have done searching and used various calculators posted in this forward and on google but kinda get mixed results. The thickness the company is saying they will use is 1in and I want to make sure this enough. Here are my questions:
1) When calculating the required thickness do you just take into account expected water or height of the tank. For example, a 30in tall tank with 1in acrylic will have max 28in of water but more likely it will be 26-27in. This can have a big impact on the output. Different calculators take different approaches.
2) How much bowing is expected? I am assuming unless you go nuts, there will be bowing no matter what? I want to avoid the horrid bowing that there have been several threads about recently.
3) Are there different grades/quality of acrylic? I know that cellcast acrylic must be used but is all acrylic equal? How does age impact this?
 
I am looking to build an acrylic aquarium with dimensions 72 L x 36 W x 42 H using 1/4 acrylic thickness. I will have a lid 72 long to with 3 cutouts to act as the access points and the brace to prevent bowing. I do not have the budget to buy any new acrylic but would like some advise as to whether or not this will work. Please advise, thanks!!!
 
Are you trolling or is this a serious question?

In the simplest answer, No it wont work.
1/4 inch thick on a tank 42 inches tall is a sure recipe for disaster. I doubt you will even get it filled before it explodes.
And you should probably start a new thread, instead of posting on one 8 months old.
You may get better response.
 
1" is good. I have 30" tall 10' long with 3/4" no bowing make sure they are using a full top rhat way it is solid. And just have the lid openings cut out. I have another tank where it wasn't a solid top and had problems
