It doesn't blow off (with a turkey blaster) nor does it come off easy. It doesn't bubble. Does not feel calcium based; It's a little slimy to the touch. It's also growing on my power heads and on the rocks (but it's not consuming the rocks). It is not growing on my substrate, which is aragonite. I've had this stuff for at least 6 months.
Tank has been running for 1.5 years.
