Timfish, you are right on the money. New tank, about 2 months for the initial set up in a small tank then transferred to a larger tank (120) about 4 weeks ago. My rock/sand is a mix of dried and store bought live rock/sand. There is a mix of snails, hermits, emeralds, a cleaner shrimp, and a wayward missing/hiding pompom crab. Only 2 fish so far a damsel and scooter blenny, didn’t want to overload while the initial algae was being trimmed. I have a small cluster of Xenias, a single zoa and a small colony of the same, a small mushroom that now has 3 new “blooms”, and a leather. All seem to be doing good. I have read about the different algae but this color was new to me.
Thank you for the sharing of the knowledge. As I was getting concerned about something getting ready to head south.
