I've got quite a bit, I'm always pulling half of it out of my
HOB fuge...
If you still need some, and if I can figure out how to ship it without it dying, I'll send you a couple fistfuls if you pay postage.
This would be out of my display tank and, as far as I know, it's completely healthy. The Ich is/was in the other tank. But if you don't mind quarantining for a month, I can send you a large tennis ball size chunk from the tank that had Ich two weeks ago.
I've got some kind of pretty red stuff also that I can toss in. It doesn't seem to be invasive...
Send me an email if you're interested. Otherwise I'll toss it in the garden, like I usually do.
