Glass/Acrylic thickness calculations

[TKoontz37]

I’m wanting to build a 500 gallon tank but I’ve been having a hard time gauging the thickness of my tank material. I feel like there are so many variables because I’ve heard that the taller you go, the thicker the glass needs to be. Is there something or somewhere someone could refer me to? I need to figure out where to get started and where I could find the materials I need.

I built my own tank 600gal
5x5x3 ft tall
1” acrylic with top
There are many variables to figure out
Maybe do a search here in the DYI section

You could get some advice from Glass Cages and/or Tenecor

Even your LFS could get you a quote. Then you could use those specs

Then your skill will be put to the test.

There are a few glass thickness calculators floating around. I played with this one.
30" deep 500-ish gallon dimensions.
Height is the critical factor..
From 30" depth; 18mm sides or say 3/4" to 24" (610mm) depth; 12.9mm, 1/2"
Now this is free standing with no cross bracing.
Basically bracing will divide a big tank into 2 smaller tanks so you can use thinner glass.

For my little example you could probably go 3/4" for the bottom if you get it tempered.
YMMV.

FOR DISCUSSION ONLY..

Out of curiosity I priced 96x30" piece of 3/4 glass...' $1091.81
One piece.

Nice build.. But the million$ question.. Did you save some,lot, no, or it cost more $$"s?
Granted things like this have good amount of $'s delivery and labor and much depends on if you cut/polish the panels yourself. Oh yea and drilling.

I was quoted about $20,000 to build this tank by 2 different vendors. It cost me about $6,000 to build. Around $5,000 for the acrylic then CNC cost plus wood to build jigs and 2 part bonding adhesive. I had the local acrylic supplier CNC the panels. I am not set up to do that on anything bigger than 3/8”. I figured if I screwed up I could build a second tank and still save money.
The costs were 10 years ago. I’m sure prices have gone up like everything else.

Well first decide acrylic or glass. Both have different requirements.
