Help! I've lost control of plant growth in my tank. It's not hair algae so I'm not sure what to do. This stuff is well rooted into the rocks and grows rapidly. It's tried to choke out some corals but I've managed to save them so far. I can keep it trimmed back off the sand so I moved all of my coral there, but I miss using my rock work. How can I get rid of this stuff? And what is it exactly?
There are two different plants growing.
