The ugly stage almost always passes. But it can take a while. I would siphon out algae weekly and do 10% water changes weekly and be as patient as you can be. I would also refrain from adding chemical cures.
I would do the water change but also do more research on this forum before any more additions. Adding a Nem to a new tank is never a good plan they require established stable tank. Hopefully yours does ok.
They are doing okay, my tank was running for 8 months already but a month ago I decided to upgrade my tank use my rocks and add more marco and did a water change first before transferring them to their new tank, afterwards it’s happening again those brown algae
There's your answer. Any time you add dry rock, it will go through some of the same stages as a new tank. Basically, your tank had already seen some of the battles for real estate among the different algaes, bacteria, archea, etc, and found an equilibrium. When you introduce new dry rock, that's empty real estate that the microorganisms will again compete over.
So to avoid it, should I water change weekly for 10%? And do you think adding a hermit crabs will they eat those brown algae? My corals and bubble tip are doing fine
You're not going to "avoid it" at this point. Just like any other algae outbreak, manually remove what you can, monitor nutrient levels and address problematic trends, and utilize algae eating cuc/livestock.
Good for you. This is not an option for everyone.
I think it's an option for most people, they just aren't aware of the benefits which is why I left the comment
