i have been watching this grow on my rock for the past couple weeks. I do have standard bubble algae that I believe I'm winning the war on but this is something totally different! It looks like it grows and has a similar form to bubble algae but at a slower rate. It is only in this spot too and dose. It seem to be spreading. Has anyone else seen bubble algae like this if that is even what it is!? I kinda like the look of it! The white and organge is really bright.
