Sorry for the delay everyone, but its in!!......finally,
i did consider taking it apart and resealing. but in all honesty it was easier to knock down the wall.
only took a couple of hours. (dont think i could strip and rebuild the tank in that time.)
stand is built again. will upload pics later but currently at work and havent brought the lead with me.
it has a couple of chips on the corners, so ill admit im nervous.
none look that bad but its still a lot of water if it does leak.
ive searched a couple of threads and the general consensus is it should be ok.
im still going to put some silicone on to be on the safe side.
fingers crossed lol.
