Along the same lines, silicone a piece of glass inside, just a bit
smaller than the bottom pane. The thickness you need depends on the
severity of the crack. This can sometimes work very well (and it's
easy). I've often read that a 4ft tank (ie: 55g) is at the edge of being
worthwhile fixing (changing a glass pane out). It all depends on the
value of your labour, how handy you are and tools and work area
available. Bigger tanks are more worthwhile and for smaller tanks, they
get hamsters ;~)

Lily,

I have just "fixed" a 4ft tank with a crack in the bottom pane. I
cleaned
the area with cleaning solvent & then applied a lot (not very pretty)
of
aquarium silicon. It was left to cure for a day & when filled no leaks!
(ps
I got the tank free from a pet shop that was just about to chuck in a
skip!

Good luck,

Sky

Needing your extensive experience!
I have the chance of getting (free) a 4ft tank and stand.
Problem is, tank has a crack on the bottom panel.
My question is - is it worth the trouble to see if it can be fixed?
4ft
tank means a helluva lot of water pressure/weight for this tank to
deal
with - should I forget about it? My understanding is that it is a
plastic-framed glass tank - would it be a matter of replacing base
panel,
or
is it still going to be too dodgy?
Cheers
Lill
