    How much weight can glass take?
    How do we work out how much weight we can safely have on top of our tanks?

    base is solid but what about the walls of the tank? surely theres a breaking point?

    I've often wondered the same thing when mounting MH's on the top of a tank, just how much can the sides take? If you consider the base of your tank, for example my 2m tank had a single 10mm base holding about 900 litres of water plus rock so I reckon there was close to a ton of weight on top of this single pane of glass, I reckon the sides could handle a fairly decent amount of weight.

    Yes sorry, I'll try not to lean on the tank :whistling:

    i was just thinking as I'm busy building the hood for my tank.
    I wouldn't want it crushing the tank.

    Hence i find myself wondering how much weight a tank can take is all.

    the fact it acts like a box means many many KG's worth of weight if distributed evenly across the glass.

    if there is a single pressure point on the glass it will crack it. like your base has to be perfectly flat same with the hood

    so weight should not be a problem if done correctly

    Well the hood is flat.... after many hours of DIY :peroni:
    Its has even got some of that soft rubber to cushion it between the wood and the glass.

    should be fine but i always expect the worst

    Calculator

    The glass calculator we use give a different glass thickness to the bottom (thicker) compared to the front & back panels.

    we recommend 2.5 safety factor as minimum then a 2 x .6 x .6 (filled to .58 = safety factor of 2.66) need a 12.45mm glass bottom and 10mm sides.
    That is without the live rock - so we do not build aquariums without a floating bottom = ensuring the aquarium can handle it all!
