Vinnie Posted November 9, 2014 Report Share Posted November 9, 2014 So I haven't done anything major in a while since the way work has been, and had to scrap a few projects along the way. Looking at building a tank for the living room for fresh water trop while re starting my marine project, anyway... The tank I'm looking at building would be 2500 x 300 x 900mm (W x D x H). now I know for a normal tank build over the 600 - 700mm height you need to go thinker than 10mm glass. With it only being 300mm front to back and good bracing could I get away with 10mm or to risky? Quote Link to comment Share on other sites More sharing options...
kiwiraka Posted November 9, 2014 Report Share Posted November 9, 2014 I'd say risky, you should probably do 12mm just to be safe... Quote Link to comment Share on other sites More sharing options...
Godly3vil Posted November 9, 2014 Report Share Posted November 9, 2014 Put it this way, I wouldn't want to be sitting in front of the tank for prolonged periods of time and I'd keep children away from it...... Quote Link to comment Share on other sites More sharing options...
livingart Posted November 9, 2014 Report Share Posted November 9, 2014 need at least 15mm for that height and span internal forces are still the same Quote Link to comment Share on other sites More sharing options...

Too bad we don't have a way of calculating glass thickness, and if there were it would be great to have it on the site...OH WAIT: http://www.fnzas.org.nz/?page_id=1635 :slfg: For a 1.1 safety factor(Just barely not breaking) you need 12mm. 16mm gets you almost 2. 3.8 is a commonly suggested factor to account for earthquakes, brats banging on it, etc. And that would require 22mm. The length front to back is totally irrelevant, it doesn't effect the forces on the front or back panes. Quote Link to comment Share on other sites More sharing options...
Vinnie Posted November 10, 2014 Author Report Share Posted November 10, 2014 Thanks to those that answered the question politely, as I didn't know if the internal force was the same or not. Will go 600mm high to keep it safe as this is going behind the couch if I build it. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted November 10, 2014 Report Share Posted November 10, 2014 Those figures are based on full bracing---either euro bracing or a steel frame, and including polished edges I think. Quote Link to comment Share on other sites More sharing options...
