I know nothing about Seiryu stones or PC1
Thanks for your comments, I hope mine breed but if not, they have such a long lifespan it shouldn't be an issue if they don't.
I bought the Seiryu stone in this bowl from PC1 or were you referring to the large Seiryu stones in my Jewel tank? Those two came from flowerfishs. Flowerfishs has some nice large ones available right now. I bought a lot of nice smaller stones from PC1.
I am completely ignorant on this subject. Just love the "mountain" look of them and think they go so well witht the spartan look that it seems most Americans keep with their HRS. I was speaking of the one in your HRS bowl. Thanks for any addit. info.
