	Black silica? gravel that began with an "A"....
Pippin Hobbyist Posts: 78 Kudos: 63 Votes: 1 Registered: 11-Feb-2004	I'm trying to find some good black gravel for my 15 gallon that will be ok with cories. I found some at a local petstore but I'm not sure about it. It began with an "A" and had silica in its description. And in the intructions it said not to rinse too much or something would happen (curse my bad memory!!). So that worried me. It was about an eighth of an inch or smaller. Also, I looked at the same gravel that was in a tank set up in the store. A lot of pieces had an orange coloration to them like the black had come off....

Its actually a form of glass (silica) and has sharp edges much like crushed glass. The sharp edges can injure your fish and destroy the barbels on a cory. If you want a black material, black tahitian sand or gravel might work. Frank -->>> The Confidence of Amateurs, is the Envy of Professionals <<<--

It does not need to be rinsed as it is packed wet and is biologically active. That is, it will accelerate your ammonia/nitrite/nitrate cycle.
