Light ON duration

[finind]

Typically how long to leave the lights ON?

For my setup as I afraid of alage or diatom boomz , I try to limit the duration to about 4-5 hrs, 4-9pm.

So far manage to have phospate, silicate, alage & diatoms under control ... I thought of increasing the duration gradually

I believe LFS display tank all turn ON their lights for very on hours

Is there any guide on recommended duration? Perhaps follow the Sun is the max.?

I placed my tank in a room. From sun rise till afternoon 4pm the room is dim as the window is not open fully in case heavy rain and nobody around. So the tank also dim.

Is it better to ON partial at least from noon onwards? Any best practice?

Can share your approach and experience?
