This doesn't explani why it has shown up here and grown very well
in fishless substrate free tanks.

Algae fix and the like: copper works the best IME,

Sure, but, H202 can be used in tanks with, say, shrimp
and it will kill the staghorn and not hurt the shrimp[1]. Copper
and Alage Fix won't do that.
