    Need some urgent advise,i recently took on the challenge of building my own tank
    YES,my first build and it a 2000X600X600 with 10mm glass all round.

    Have bottom braces front and back aswell as ontop on the corners and across the middle.

    Tank has been running for a week with no issues UNTILL today!

    Came home now and the two middle struts(braces has popped loose)seems like 10mm gap now from where it was attached to point where its hanging now.

    front pane has flexxed so now im worryin......

    *** do i do?

    just try to add more bracing?

    no fish in yet

    Agreed, drain re-glue with extra bracing. Remember when you add flow to the tank the strain will be even more, just saying incase your flow wasn't on yet.

    drain it soon so as to get the pressure off it. Id be concerned with 10mm glass over a 2m length, so youd def need to up bracing significantly and make sure that its propperly cured before refilling

    Drain to 200mm if there is stock, what lights are used above the bracing?
    I think you are going to have to toss that pane, @Leslie hemple and @Nemos Janitor would know best

    Is that the center of the tank? Are those the only braces you have on the front pane besides the corners?

    If so consider bracing more, and using wider pieces. What do the Guru's think? My 1.5M's center brace is 20cm wide, those look like 5cm pieces.

    Those two centre braces are way too small.
    There is not enough cross sectional area on the silicon to counter the forces pulling it apart.
    Need a much larger brace, say 30cm wide with a section glued underneath it to increase the contact surfaces.

    That centre pane is fine, it will return to its original shape as soon as you empty the tank

    yeah, as long as that glass didnt crack it will be fine, normal glass is quite flexible hence using it for aquariums and not using tempered glass which would have shattered in that situation and you dont need to reseal, just get some more bracing.

    just emptied the tank to about halfway and the front pane has regained its form.
    the two middle bracing was like 5cm wide and the corner bracing was 10cm wide.

    SHould i add more/thicker bracing to top aswell as the bottom?

    Rather do euro bracing right around the top and if needed or recommended, one centre cross brace of 200mm or so. It's not about whether the glass can take the flex, it is about what happens if a kid bumps it or a piece of live rock falls over and hits it...

    Rather go for euro bracing around the top..on that length with 10mm glass with those braces will not hold..Good luck man...

    I would suggest Euro Bracing right round the tank. +/- 70mm wide front and back the whole lenght of the tank on the inside of the panels, then use the same width for the sides and finaly a centre brace of +/- 150mm - 200mm and you should be okay just remember to let the silicone cure before refilling.

    Thanks to all the input guys,so all i shoudl do is brace the entire top of the tank with atleast 15cm wide struts,across corners and a nice 20cm brace across the middle?

    Going to be real crap tow work inside the tank with all the braces:p

    AoR was correct,front pane is 100% straight again.

    Also how long should silicone cure for,before adding water?

    I would suggest nothing shorter than 5 days but let the tank builders give you suggestions.
