I have done a search and have seen it in stores, so i have come to the conclusion that flagstone is safe to use in tanks. however, i have (2) main questions:
1.) what does it do to the water parameters? I would assume it would raise the kH?
2.) does anyone have any good pictures of a tank that uses flagstone? I will be using it in a planted cichlid tank and plan on making a bunch of nice holes and caves...
