    I need some help.


    I have a 1.5m tank that is about 6 years old. Recently I have noticed there are some small bubbles starting to form in the silicone joints of some of the panels and the one side panel is not flush against the other panel but is pushing out about 1mm at the top of the tank .I have also noticed some algae growth underneath some of the silicone joints.


    I do not want 500l of water in my living room. Would it be wise to just remove the silicone in the corners and reseal or would it be better to take the tank apart and re-silicone.

    welcome..

    to answer your questions it would be easier if we could see a pic to determine just how bad the joints are.. but if you are intending to start this tank up and have it running for some time then perhaps a resilicone isnt such a bad idea..

    you coule assess the front panel and see if it is scratched and needs replacing and you could redo the tank in black silicone if you like that look.. the options are endless..

    but take the time now to do the things you cant do later... and set it up properly 1st time :)

    Resealing has never worked for me before :(... new silicone just doesn't stick well on old silicone. I say a rebuild would give you more peace of mind:1:.

    Hi

    Cut the whole tank apart "boude & blaaie" and reseal - patch work is just that. You would only postpone the inevitable. So rather do it right the 1st time

    Very funny Leslie :nah: im referring to the point were the old silicone and new silicone meet. If you just sealing one side there must be a point were the new and old meet. That is were i have picked up a leak many times :blush: so i eventually rebuilt the whole thing then it lasted for years :thumbup1:, till i sold it.

    just kidding.. i am advising a strip down silicone removal and reglue/rebuild.. all glue must be removed with a blade untill it is 100% clean wiped with methys and then put together again..

    DUDE :eek: If those air bubbles were not there before and they formed while that tank was full, you urgently need to empty that tank before it starts to leak. and as we have already advised, re-silicone the whole tank.

    Air is getting in there because the glasses are being pushed apart by the force the water is exerting against it.
