Silicone Sealant For Tanks.

Is the type you can get from hard ware shops safe for use in an aquarium or is there a special type?

Most hardware shops sell it, but its not the normal type. Check that the label says its save for aquarium use.

Thanks, i thought there was a difference! I take it most LFS would stock it?

Also, can you get one's that work under water? i.e. I don't have to empty the tank.

No sure about that, I think normal aquarium silicone does have something in it that will not be good for your fish, only when it is completely curred its aquarium save

If you are re-seaming a seam or similar, the tank needs to be empty and completely dry. You need high modulus silicone; the type you see in the diy shops usually are low modulus, and contain anti-fungicidal additives, which are toxic to fish. As far as I know, there isn't a type that can be used underwater.
