It's a bit of a job but it isn't too hard to reseal a tank. The only real effort is removing the silicone, but if you have the right tools it's not too hard. I bought a pack of 100 industrial razor blades off eBay for ?5, and a little kit for making a neat job of the silicone beads (fugi or cramer kit). The silicone itself was about ?4 per tube for clear aquarium grade silicone, and the gun was ?3 from a hardware shop. Total cost about ?26, or ?12 if you don't bother with the fugi kit (you don't really need it if you're not too bothered about how it looks).

To remove the old seals you run the blade under the silicone all the way round and pull it away. You then remove any excess with the blade as best you can, and rub it with a cloth dipped in household ammonia or a solvent cleaner such as isopropyl alcohol (available from chemist). Unfortunately you will have to remove all of the seals as you can't repair it as old silicone and new silicone don't stick together well, so there will always be a gap or a weak point at the very least. For a 6 foot tank this will take a couple of hours. Remove one panel at a time and you can probably manage it on your own.

Once all of the glass is dismantled and cleaned (the cleaning is really important) you'll need a friend to help you put it back together. If you do decide to go for it I'll point you in the direction of a website that demonstrates it better than I can. You need to work fairly quickly so just plan it out in your head. I found it handy to have some 90 degree angle clamps to hold the corners together but make sure you use something spongy in between the metal clamp and the glass to stop it slipping. This part takes about 15 minutes, then you need to leave it to stand and cure for a couple of days without moving it.
