Coralline algae on snail

[Plunder]

Today I noticed some of the shells of the snails seem to be growing something on them. Could this be some coralline algae?

Very likely-- it's a common place to see coralline early on.

That would be awesome! I set my tank up a month ago and added some coralline boosting tiles from IPSF two weeks ago. I know this question gets asked a lot and its different for everyone, but in general, when I might I expect it to start growing on my rock if it's growing on the snails?
