Just when you think you’ve found a shortcut

I just keep the blue lights on. I have two AI primes and a Fluval marine 3.0 46” light across the back. At first I thought this was coaling cause I couldn’t rub or blow it off the rocks. It’s algae I guess. But just strange it’s growing without any white lights.

Blue lights definitely grow algae just as well as white lights. Not sure why people say that. But that’s normal and the beginning of coraline algae and will eventually cover all the rocks and change colors. Rocks are not meant to stay white. Relax and enjoy the show.
