I want to add a big hunk on Turquoise or Malachite to my 75 gal tank. I don't know much about turquoise, but I know that Malachite dust is poisonous, but is ok to handle otherwise. Will either of these stones leech anything into the water?

Holey rock can raise the ph and hardness of your water.

TankGirl said:As long as you have the rock in the tank the change will be there, but it is very subtle. It is not worth trying to add media to the filter to counteract - much simpler just to remove the rock.
It is not going to take pH 6.8 water and in a week turn it into pH 8.0, but it might bump you up to 6.9 or 7 pH and increase hardness by a degree or two.
