My local store got some Dragon Stone in (also called Ohko Stone) for a decent price. Since no one seems to know what the scientific name of this stone is, I was wondering if anyone can confirm if this stone affects water parameters in anyway. Because of how it looks like it's eroded I'm concerned that it might be made of soft limestone which would affect the pH.

Thanks,
Harry

Thanks. That's what I thought. Weirdly enough though I found this comment on the Aqua Forest website (which seems to be the main ADA reseller in the US):

This rock is inert and will not affect the water chemestry of your aquarium.

Here's the website: http://www.adana-usa.com/index.php?main_page=afa_product_info&products_id=6

Maybe it's not limestone after all.
