Where do I buy black silicone?

[dasouljah]

Hi, I've been wanting to buy black silicone to stick a cork bark background to my tank. Been to self fix and home fix and they only had silicone cartridges, the ones that you load them into a gun to apply.

Anyone can direct me on where can I get my hands on it? Any recomended brands?

Buy it from custom tank makers? They are sure to have it, and it's sure to be non-toxic aquarium grade silicone.

Otherwise you might run the risk of poisoning your critters.
