Big Al's sells the Allglass brand of black silicone which is nice.
its a nice dark silicone, the same that Aqueon (Allglass) uses on their bowfront tanks (and my 150g tank that I got custom done from them in black seal
).
some 'black' silicones are more like a grey colour, and they don't look as good..
personally,I think black silicone looks 10x better on an aquarium, and doesn't stain with meds or show algae growth overtime like the clear does..
