    Hi all,

    I was transporting my mothers tank when I found a crack on the base glass, not sure what caused it, it was ok when I loaded it, perhaps a bump or heat of the sun light?

    But how should I fix it? Chris (Northlands):thumbup:, was kind enough help me out with some 10 & 12mm glass pieces about 120mm wide, as I was there getting some worms for my friend when I noticed it.


    [​IMG]


    Chris suggested I "tile" it using say 150mm x 120mm pieces.


    PLEASE HELP

    i would add the glass on top and make sure there is plenty of silicone so water cant seep thru, also add a 6mm base, remove the polystyrene and clean the base then add the 6mm so the crack is sandwiched in between, i just did that to my 4ft sump and sofar no leaks, will see over night

    If you don't want to replace it - i.e. go to all the hassle of removing the broken bit, i'd sandwich it between two new panes of glass the same thickness - it will make it heavy though.

    Justin. I agree with the guys. But if I were you, I would change that base. Remember that tank holds 600 litres of water on a 1m area bud.

    I've only got a decent size piece of 4mm to put on the lower side, but that would make the base un-even, would the styrenen just take that up?

    What I have is

    2 pcs 120 x 450 x 10
    2 pcs 120 x 900 x 12

    and some pieces 4mm about 400x500

    :( to do that would take forever and plenty work, probably easier to just by a new tank?

    you coming to help?:)

    It the base so the bracing and the overflow has to be removed....
    basically means stripping the whole tank... do you not think the putting pieces over the top would work ?

    why not send it to northlands and ask them to put a new base on?
    thats cheaper than buying a new tank and you wont have to work on it.

    Not a problem I can come and help.
    Another option would be to get 2 pieces of glass. One big to fit inside the tank (between the bracing) that will cover the entire area, and one for the otherside. As the guys said, 'Sandwich'. My main concern is the crack running in another direction.

    well option one is to tile and option 2 is to strip and replace.. the question is ? is there any urgency to the situation? eg: have you got fish in a bucket waiting to be placed back in the tank? if not go the latter and do the proper thing and replace, believe me knowing that you patched the tank will ug you forever even if you cant see it..

    The crack has run to the edge on both sides, so can't run anymore, only 1 other little run, but it facing to outer edge, which would be covered by the new supporting piece.

    I've just given it an attempt to try seperate the bottom off using a length on steel fishing trace, no chance, the glass has no space between them to get wire in, it just keeps sharing the trace on the glass

    Looks good man, should work, as long as the base doesn't flex with the weight of the water ;)
