Activated Carbon as Substrate

[nagukush]

Hi Friends !

I'm desperately searching for a Black Sand Substrate for my new Frontosa Tank (to sprinkle it on top of the White Sand - to give the Salt & Pepper look) but I cant seem to get it anywhere here in India. Just wanted to know if its ok to use fine grains of Activated Carbon as a replacement for the black sand.

I understand that it will adsorb a lot of stuff at first and may leach it out after sometime, but after that wont it become deactivated and inert ? Wont it be safe then ?

Kindly guide me friends, as I'm desperate for that look.
Thanks and Regards
Kush

I have read that the idea of activated carbon leaching out its nasty chemicals are a myth. Personally, I think that should be correct, but it would be up to you to do the research and see if you are willing.
