Aquarium Advice Addict
Help! What is this stuff? Since I added my LTA, I've started seeing this stuff. It looks like algae, but it's raised. I had some new red algae on the sand a few days ago and scooped some of it out, unfortunately disturbing it so now some is in the sand, as opposed to on top. I noticed that air bubbles seem to stick to this stuff.
Anyway, this looks like the same stuff, but it's raised. Should I be concerned? If it's algae, should I be removing it?
