Acrylic thickness on a tank..

  • We are currently upgrading MFK. thanks! -neo
Yes, 1/2" is common in 24" tall tanks. I see 1/2" to 3/4" on 30" tall, I would go 3/4" on anything taller than 24" IMO.
 
My 600 is 1/2 inch

Yes 1/2" acrylic will be good for a 24" tank height. The length and depth (front to back) doesn't matter much

Does that apply to glass also? What would be a max front to back for 1/2" glass/acrylic?

There really isnt a max front to back. Water pressure only gains as it gets taller. A 72x24x24T and a 120x48x24T would both need the same thickness in acrylic and would be exerting the same amount of pressure.
I can't remember the formula exactly I think it was .434lbs/in2 per foot of water column
 
When I custom ordered my 560 from Pro Clear, they told me to go 1 inch.
Tank is 120 x 42x 26
Monster weighs 900 lbs

man i've been looking for an the answere to this question for awhile :) thanks man :thumbusp:
 
Close its 2.31 feet per psi or feet x .433= psi at the bottom. So in this case its 2 X 0.433= 0.86 psi on the bottom of the tank. Keep in mind that the pressure will decrease the higher up the tank you go. Here is the real mind f*==.... 72" x24" is the dimension across the glass. If you just calculate the pressure that its exerted across just the bottom of the glass in square inches it would be 0.86 x 72= 61psi pressure across the entire bottom seam on one side of the glass. You have four sides right? Multiply that by four and that its the total bottom seam standing force 24/7. Still want to trust 1/2"?The formula for calculating the total force across the tank escapes me at the moment. But I'm sure you get the point. Not the kind of thing I would risk considering the repercussions for a screw up IMO.
