    What is the largest tank that I can build in 10mm glass. It would have 2 braces going over the top and rim bracing against the sides inside the bottom. Total height will be 600mm with the water level at 550mm. The width will be 800mm.

    So ????mm(L) x 800mm(W) x 650mm(H)

    the calcs all say between 1.2 and 1.5 for a safety of 3.6-3.8
    if went from 550 to 500 and 650 to 600 you could get 3m length with a safety of 4.2 in 10mm

    Broder - my 2 metre tank is in 10mm glass, with front-and-back bracing, and a centre brace of 12mm (150mm wide).

    Thanks, was thinking that too....but not sure and I don't want to really brace in the middle.

    Broder just for interests sake....I ran my current tank for close to 5 years without a centre brace 2m x 60cm x 70 high. It had a brace but this got dislodged while filling the tank or the previous owner already had it like that...can't remember, but anyways the bow that front glass made when looking from the side...eish... fellow reefers quickly told me to get it sorted out.

    I've also seen a 3m tank that popped a few month after being built in a pet store. It had bracing similar to what you intend doing. I just don't think the tank builder fitted the bracing correctly in the first place.....so just make the end parts that overlap/connect the front and back panes have a lot of surface area to stick to.

    My old tank was 2m x 75 cm high x 70cm wide and was made from 10mm glass, but it did have some serious bracing at the top.

    Thanks adee. I'll have euro-bracing going around the top as well.

    What was done on my tank was to cut shourt lengths of 10mm glass (about 5 layers) that formed 'wedges' this was sandwhiched togther to form a 50mm surface area and that was stuck below the edge of where the braciing would lie......on either ends where the cross bracing will be placed. the cross brace then covered the edge on the glass plus the top layer of the wedge that was glued on the inside.

    Hell, I hope i'm making sense?

    Makes sense Adee.

    @ Sweetnsour, I think Adee probably did it without eurobracing.

    went back to some old tank build pics

    That "step" portion was actually used (previous owner) as the rest for two large sheets of glass (splash screen of sorts) ... you need not go much wider than the cross bracing strip. but the longer- wider you go it will add to the sticking strength of the cross brace onto the front and back panes.

    the biggest tank i have built in 10mm is 2.5 x 1.000 x .700 standing at pampered, in my opinion it is soo big and i would change the width to either .900 or .850mm if i did a future build of this size in 10mm..

    i also advise maximum bracing on a tank of that size, straps over the center are unfirtunatley a must unless you go with 19mm..

    a friend of mine and i built a 2.5 x 1.000 x .800 out of 19mm it would be the better option for long term success in a tank of over 2m and 800 wide..

    Thanks Leslie. I'd rather build a smaller tank in 10mm glass than a larger one in 19mm. The difference in viewing and especially photography is so much better in the thinner glass always.
