Brown algae? Something else? Advice on what to do? Tank has been running for 6 months, just started lights the past couple of weeks when I added corals. What should I do? Nitrates are 10, temp 78-79, salinity 1.025. Corals and fish doing well.

if your tank is that old i would think its probably not diatoms i would look out it could be the start of dinos
Yea diatoms dont really need light like other algaes just silicates in the water thats why you mostly see them in newer setups once the silicates burn out you generally dont see them anymoreThat was my first thought except he said he just turned his lights on...
