    Oh, in that case, please change the tank. Cracks are weak points and the weak point will grow. The silicone will not be able to prevent the crack from spreading. It's mechanics of solids... Unless you fancy giving your floor a good wash with aquarium water suddenly... No point saving this kind of money...

    i agree that you should get a new one.. i guess in the long run, that silicon isn't gonna hold that stress point for long..

    maybe can use this chance to upgrade? haa...

    freezze, that was the same kind of crack I saw. Do the necessary now. Luckily yours hasn't broken open.

    Definatly agree with squee, a crack like that will widen over time. If you want a cheap tank, head over to Kingfisher, Ian's trying to get rid of some old 3 footers.

    Freezze, its your choice... But for the safety of the stuff near your tank and your family, please change the tank. Sometimes, a crack can hold for a long time but it is a time bomb that can go off ANYTIME.

    Here's an alternative for you.

    Take a small glass/acrylic square.
    Apply silicone to the centre of the square
    Press the square HARD against the crack to create a seal.
    You should have excess silicone oozing out the sides of the patch.
    Leave it to dry.
    Apply more silicone around the patch and smooth over with your finger.

    And there you have it, a very strong(albeit makeshift) patch that'll last longer than the rest of your tank. seriously, that'll probably be the LAST part to give way. And remember to clean the glass before using silicone


    [Disclaimer] That's what I used to fix a FOUNTAIN. Not a fish tank. I will not be held responsible for anything that goes wrong. But the concept is almost exactly the same so I wouldn't worry.

    Still think it is better to be safe than sorry. Especially when you have to end up cleaning up a couple of hundred litres of water, sand/gravel, dead plants, fish off the floor and not to mention running the risk of it bursting when no one's at home... There goes all the stuff near it, soaking up tank water... And then the electrical equipment nearby...

    My usual paranoid 2 cents worth...
