Hello! I have searched everything I can think of and I can't find any pictures that match. I thought this was coraline due to coloration, but there are bubbles. My sally lightfoot takes care of majority of them at night, then they come back in full force. I cut my extra coral lights today, but I want to make sure what this is and then proper treatment. Water is perfect, t this tank is ~3 months old.
Thank you so much in advance!!
