I found a nice piece of Granite at the seashore not a big piece, but it has a round hole right through it, it's been out in my garden for some time, it was a bit green, I've scrubbed it with water and used a toothbrush and soaked it in a bleach and water solution, itscome up nice and white, I've soaked it in water for 24 hrs, do you think it would be safe for my aquarium.
