You never need to buy a new tank.

If it springs a leak, then it will be because the Silicone Sealant has gone.

Just use a sharp knife to cut off as much of the surface sealant as you can
and then buy some Silicone Sealant from the local hardware store and glue it
up again.

Of course, it takes a week or so for the silicone to cure, so you need
somewhere to put your fish while you do it. Perhaps you should buy a new
aquarioum to hold the fish while you fix the old one

I ask because I the seals on my 29 gallon planted tank seem to peeling at
the
edges. I bought the tank new in 1989, and it has been up and running
continuously since. There are many algae-eating critters in the tank
(bristlenose pleco, various species of snails, an oto or three, etc.), and
I
suspect one or more of them have been gnawing on the seals to get at the
algae
growing on on them.

Is it time to buy a new tank, or am I being paranoid?
