Im dealing with what I think is diatom algae. It's brown and covers the rocks and sometimes the sand. It brushes off very easily. What's weird is that every morning it's gone. With the lights off all night it goes away but within a couple hours of turning the lights on it comes back. I'm familiar with diatom algae showing up during a nitrogen cycle but my tank is about 4 months old.
I do weekly water changes and am running a protein skimmer. Water filters through active carbon and purigen. My numbers are all very low.
What's goin on here and how do I control it??
