oh darn

If the tank is quite old, it is better to probably buy a new tank, but first it the leak is from silicone then it can be re sealed, with no probs. but if the glass is cracked IMO get a new tank.

I think there are a number of factors to consider.... i.e. where is the leak? do you have somewhere else to keep the fish while you repair the tank? how big of a tank are we talking?

Is it the silicone or a crack in the glass? if it's silicone you can just have (2-5 days)... if it's a crack you can just have a new piece of glass installed over the broken one - this only makes sense if the crack is on the bottom or the back - both places where it is easy to hide.

I have a 20 gallon... broke the bottom and had a new piece siliconed over top. Have had that thing running for 6ish years now since it happend and never had a problem.

Thanks for the info Decz. I have a 40g breeder with the bottom glass cracked. I think I will try this and see how it goes.

you can pick Silicone up at walmart in the automotive section. That is where they keep it at mine.
