    You can use the Calculator on this Site and you can adjust the Safty Factor...:)

    One last thing... Calculaters said 10mm is good, does the thickness of the base matter? can i go 4 or 5mm on the base?

    I would go with the 3.8 safety factor and stick with the 12mm quoted...:blush:

    PS...remember all the LR and sand still to be added...don't go less on base...

    no you cant with do 4-5mm base it will crack as the glass isnt strong enough to support the weight of the water. rather stay with the safety factor and you wont have the hassle of swimming in your own house:)

    Base should be double that of the sides.
    Best option

    The idea of my house being flooded and critters dying gives me the heebies. Dude, don't skimp on it, rather overengineer or go for a 2nd-hand tank.

    i built the similar size tank, 500mm high , i used 12mm all round and the tank is rimless, the bottom is braced. but at 600 i would add some bracing

    i personally have had a tank of this size (.750mm width being the only difference) in 10mm well braced ...

    12mm is fine and there is no need to go double base as it will add to the systems weight making it a nightmare to move if need be...

    For what its worth, only the depth of the tank determines the glass thickness needed (base - as this is unaffected by bracing). For my 800mm deep tank with a double base (each 10mm glass) this was not enough and it broke. With three 10mm bases glued together it was strong enough. I would not feel comfortable with 12mm for the base. For the sides yes.

    I would go for 24mm Base (floating ) 2 x 12mm stuck together and for sides I would go for 12mm Braced. If done correctly you can leave out the centre brace. Just my 2c

    uh ohh,i am agreeing here,lol.

    The base has to be thicker then the walls, you can't fight gravity!

    You will loose!

    Gravity pushing down on the water will press out against walls a bit harder but the base carries it all and the supports including Styrofoam will change shape and your glass if thin will not like that.

    Calculate the weight of your tank and sump together and make sure that wooden floor can handle the weight...
