Ok I think this is part of the ugly stage. 4 weeks ago had the brown diatoms and it cleaned up. Now noticed this starting to cover the top of rocks and sand. Unfortunately I'm still waiting for my Foxface and Yellow eyed Kole Tang to come out of quarantine (2 more weeks) to help controling algea growth. Any feedback on how I am progressing or what I should do. Bellow are the tank parameters. Thanks for your feedback.
Also forgot to mention 3 weeks ago I seeded my tank with Purple and Pink Hellix coraline algae and this past weekend I started my refigium with live sand and chaeto.
