Should I turn my lights off?

Interesting. I did the opposite. Lowered the intensity of the lighting and and used bacterial booster to get started. I got little bit of ammonia, then nitrite spike and now just low nitrates levels. No diatom but starting to get coralline algae. Should I be concerned about the lack of diatom?

Turned lights on 4 days ago and already rock and sand bed are getting covered in brown diatoms.

How do I stop this from taking over? Do I let it play out? Do I turn my lights off?

I do have an anemone in here so I can't leave lights off for too long...

150 gallons system
0 ammonia
0 nitrite
0.05 nitrate

System is 3 months old and parameters have been stable for 2 whole months.

Livestock are:
2 clowns
1 foxface
1 bluethroat Triggerfish
1 cleaner shrimp
1 anemone

I know I'm heading for the ugly stage, but can I stop it in its tracks/avoid it?

Hello
What I did was to just run lights in my sump for my fuge, so the ugly phase only occurred in there.

Now I have no algae, and like 15 mangroves on my sump along with some chaeto
