I saw on the original post that we could buy through the forum, but I am new to the forum and can't figure out how to purchase it. Could you fill me in?
Just send me a PM with what you want and I'll give you a total. Then I can either give you my paypal address or send you an invoice that you can pay with a credit/debit card.
The video up yet?
I might try but since you said it will produce powder when rub together, so what is the right way to clean them? It seems very fragile.
They aren't terribly fragile. Especially not the Spheres. They powder about the same as normal ceramic media. You get that same little bit of dust at the bottom of a new bag that you would with ceramic media.
To clean them just run some water over them. They flow water through them well enough that even a simple backflow will wash most everything out of them. If you really wanted to scrub them, I'd use a toothbrush or something similar.
I haven't been able to get a video done yet. They sold out before I could play with more than a few Spheres last time. I'll get it up by the beginning of the week now that I actually have enough in stock to take some for marketing/experimenting/my own amusement.
