    Hey masa
    I started filling my tank with tap water to test the plumbing and set all the flows etc .when the water reached the over flow leavel,I noticed there was a bow in the glass. Then on further inspection I noticed the bracing pieces on top of the tank had popped off when tank was bowing.

    Do I lower the over flow box ?
    Or do I add braces at the bottom of the tank

    im using 6mm glass tank dimensions -100cm x50cm x54cm high
    The base is 10mm should I get thicker glass for the sides too?

    Rather safe than sorry, 6mm is very thin, you could add extra braces, somewhere there is a tank glass thickness calculator google it and see what it says the glass thickness should be

    I gave a tank to Fred d that is 13 years old made from 6mm glass. The dimensions are 1.2m x 500mm x 600mm (high) with water at 500mm. We braced the top and bottom and it has lasted rather well. Fred d please take a pic and post it of the bracing please.

    Hey can you post a pic of your tank so we can see what the current bracing looks like?

    I would but the bracing popped off when the tank bowed. Basically I had 3 pieces going width ways across the tank not length ways could this have been the problem?

    Im thinking of getting some aluminum angle iron and fitting it on top of the tank and pop riveting flat bar across the tank but not sure it will help as im scared with the pressure of the water the glass might break?

    Okay so you need to add 2 strips down the length of the tank then add the current strips at the top of them this should do the trick

    You can also add 2strips on the base along the length for added strength

    how wide are the braces going across... if they are too thin they might not be able to hold the tank

    the width of a brace that goes across shpould be 10-15% of the lenght of the tank... in your case ~15cm aprox. anything less than that and it will pop off

    maybe the brace was not glued (silliconed) properly. you have few options

    1) use only one brace but make it as wide as you can (15-20cm)........ RFOTP* - medium (if brace
    fails)
    2) make two braces going length wise which are aprox. 10cm wide and made of 2 x 6mm sheets joined
    together ..........RFOTP* - medium (because of overall tank glass thickness)
    3) rebuild the whole tank using 10mm glass and use length wise brace........ RFOTP* - none

    * RFOTP - risk factor of tank popping
