Does anyone have any experience with Ohko stone? Is it truly inert?

Thank you

I haven't used it, but yup it doesn't affect water chemistry.

I have used it. It's gets a little "chalky" (more like clay dirt) when you wash it and first fill up, but it doesn't affect water chemistry.
Just switched out driftwood for ohko few weeks ago. Definitely wash it thoroughly as the other poster alluded to. Seem to attract green algae rather quickly in my tank.
