Ira Posted December 11, 2006 Report Share Posted December 11, 2006 I think it should stabilize the PH somewhere around 8.4. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted December 11, 2006 Report Share Posted December 11, 2006 I think it is sandstone rather than limestone and therefore may not make the water as hard Quote Link to comment Share on other sites More sharing options...
meesheelly Posted December 11, 2006 Report Share Posted December 11, 2006 Yeah limestone is really hard. I dont see much luck sculpting it. Quote Link to comment Share on other sites More sharing options...
Hazara Posted December 13, 2006 Report Share Posted December 13, 2006 LOL I've cut through Oamaru stone with a handsaw..... But I guess you don't mean that sort of hard? Quote Link to comment Share on other sites More sharing options...
