On light Twice daily ?

[Ding]

I have a 3ft LED light box (having both white & blue LEDs) for my 4ftx1.5ftx2ft soft coral marine tank. I turn on the light twice a day. It is on from 6am to 9am and 5pm to 11pm. The reasoning of such schedule is because I view my tank during these two periods. I don't whether such schedule will have any side or bad effect on my corals and fishes. Currently, my corals and fishes are doing ok and I am fighting a high nitrate level (50ppm) problem in my tank.

Any advice from anyone? Thanks.

Bro most of the corals rely on lights for food. 12 hours or more

I think Corals and Fishes were be more comfortable having the same type of timing as human do.

There is time for rest and time for photosynthesis.

For viewing purpose, I have set my timing from 1030am to 900pm...

And I set to moonlight so that even in middle of night, I could do some viewing

though moonlight was found to be of no specific benefits for them.

Since you are on LED, I think you could set the schedule too
