I've got some really great purple coralline algae growing in my tank, but i'm moving in a couple months. my question is, when I empty the tank during the move (i'm only moving like 2 miles away) will the coralline die when it's dry for a couple hours? I've also got some green "hairy" looking algae growing on the foam pad of my HOB skimmer, it looks kinda cool, and doesn't seem to be harming anything, so I've just let it be. it looks kinda like cheato algae, but I've never bought any....will this just grow out of nowhere? or should I be worries about it?
