I set up this tank 3 weeks ago and now I am seeing brown diatom algae on the Anubias leaves. Is this normal for a new tank? Should I reduce lighting hours or just wait it out? Currently running 8 hours of light per day.
Totally normal for new tanks! The diatoms usually go away after 4-6 weeks as the tank matures. Your nerite snails will love them.
