I have used cement and large particle sand to cover seams in my aquascape, like in the bulk reef supply NSA video. I am wondering if coralline algae will be able to grow on top of that sand that is glued down? I know it doesn’t grow eel on regular sand beds so is it different since the sand is glued down and doesn’t move?
Here’s a pic of a spot on my scape for example.
