That's very interesting! I wonder if the age of it has anything to do with it. Since that's the only tank its happening in, I bet it is the FloraMax - which is only in that tank. I'll be breaking it down in a few months and I'll scrap the substrate then.
I find your dyeing experiments fascinating - thanks for sharing that...
