What is this?

[SaltyCajun]

Newbie here… started new tank cycle a few weeks ago. What is this brown stuff? Thanks

Difficult to say. It is a new tank, and I do see some algae beginning to show up. It may be algae. Difficult to say without a clear, zoom shot.

Maybe diatoms, but it could be something else.

This makes sense considering I am 1-3 weeks in to a new cycle. Need a better filter too. Need to work on sump system.

Should I remove this or just let it go for now? Should I test the water? Should I add some snails? Thank you!

Diatoms, just part of the cycle

Likely diatoms. They consume silicates from the new rock, and will go away on their own. Part of the process. Welcome to Reefing!

With diatoms starting to show, yes, it’s time to add a clean-up crew. Make sure to get snails that right themselves so they don’t end up dying, and not too big so they don’t hurt your corals.
