Acrylic Thickness to High Ratio for DIY Aquariums

So I am going to build an acrylic aquarium, and I have a question. But first some info...

My dimensions are:

Length (Front): 26.5''

Height (Depth): 12.7''

Width: 9''

This will give me a little under 13 gallons if I am not mistaken. I have found a height to thickness chart for acrylic, shown below.


I took this info from another forum from http://www.cichlid-forum.com/articles/diy_acrylic_aquarium.php

So in your opinion would 1/4 inch acrylic suit my needs relatively and hold together nicely?
I will be using "Weld-on 4" to bond the acrylic, and use acrylic brackets connecting front panels to back and side to front/back. Do you predict problems?

Tell me what you think. Trying to save money and if this will work if done right, I am going to try it.

Thanks

Personally I'd use 3/8 but you should be ok with 1/4 so long as you don't bump it real hard. Also I'd suggest using weld-on 40, tilt and pour method as weld-on 4 can/will become brittle over time.

Really ? I thought the bond becomes stronger over time (with Weld-on 4)?
