New to reefing—I bought used reef tank with livestock. I’ve had if for about 3 weeks and have a question on this brown algae. When we moved the tank it had a phos spike to 0.4, and started getting brown algae. I got a phos reactor with GFO running and have since brought the levels down from 0.37 to 0.17 to 0.03 to 0.00 over 2 weeks.
Questions:
1. Is this algae a bacterial bloom or diatoms? It was fairly wide spread on some rocks, walls, and sand bed. It’s since gotten better but still going strong on this one branching rock. Can I just scrub it off or should I wait it out?
2. I stopped the GFO reactor after it read 0.00. Is restarting it with a smaller amount of GFO a wise idea or should I just wait to see if elevated phos levels return?
Any help is greatly appreciated!
