Increasing light Intensity throughout the day.

[dreamscape]

My par for example with the whites/blues on are at 150 set at 40% intensity. When the whites turn off leaving only the blues, the par decreases to 100. I then increase the intensity to 60% to ensure the par remains even throughout the day. Is this right or should I keep the intensity at 40% even with the lesser par with just blues on?

I have a total time of 13 hours. Ramp up and down with 5 hours of peak lighting in the middle. If that helps.

Really difficult to say considering it depends on your system, where your corals are in the tank, etc. Always better to keep lights lower and work your way up then to cook the corals.

My schedule right now goes

7 am - 0% white 0% blue
9:30 am - 10% white 20% blue
12:00 pm - 20% white 40% blue
5:00 pm - 20% white 40% blue
7:30 pm - 0 % white 15% blue
9:30 pm - 0% white 0% blue

This will be for lps and softie tank.

Better to keep the same, or if you want to increase to 60, do so slowly 1% per day.

This is the distinction between PAR and PUR that not a lot of people think about. Your blue/white 150 and your blue 100 has a similar PUR since corals for the most part use the blue spectrum so many of the other spectrums in the white is for aesthetic only. Coral doesn't use a lot of them

If you have a sineye par meter it can also measure pur, that probably will be the best way to know for sure how much you should adjust.

Im curious if you increase the par via intensity due to the decrease in par when the whites turn off and only the blues remain?

Do you increase the intensity due to the lost in par when the white turn off and the blues remain?

Blues are heaviest as my intensity is lower. Almost to mimic natural lighting. Peak hours is when my intensity is highest and lights are the whitest.
