iisfaq Posted October 27, 2005 Report Share Posted October 27, 2005 Is it safe to use Gibston Valley Schist in my tank? I know I will have to scrub each peice to remove the dust and other stuff on it. Also does it adjust the PH or hardness of the water?

Caryl Posted October 27, 2005 Report Share Posted October 27, 2005 I don't know if there is anything special about the schist in that particular valley but generally schist is safe to use. Good for stacking to make caves. Quote Link to comment Share on other sites More sharing options...

Good for stacking to make caves. Probably nothing but marketing... I got a small bag from a supplier in Christchurch for free so I just wanted to make sure.

Caryl Posted October 27, 2005 Report Share Posted October 27, 2005 I think you will find it is also inert. Quote Link to comment Share on other sites More sharing options...
