I have 2 photon 32's over a 6' 150 gallon (20" deep). Lights are only about 6" off the water and I have removed the optics. Due to bleaching of almost all I have dialed it back to max of 40% blue and 25% whitest for 3 hrs on total of 10 hrs ramp up and down (first and last hr moonlights). I went to this after max of 60-40 then seeing some improvement at 50-30.

Question is: does this seem like too low? Or are the lights putting out enough that this should be ok long term?

Not at all. I have a photon 48 on my 90g at 8 inches above the water. I was at 75/40 for about 10 hours and noticed some bleaching and such. I cut everything back to exactly half of the intensity at 37/20 and things are better. I may even dial it down more.

But can it be kept at these levels for long term success?

Definitely, there is no need to raise the intensity if you are seeing good results, especially for lps and softies. The lights are very powerful so there is not really a need to go to full power.

On my 75 I've had them like 6 weeks and they are at about the same 35/20ish

How long are they at 35/20 for? The lights are ridiculously bright. Very deceptive. I am concerned about over saturating the coral [emoji30]

Are you keeping SPS?

Yes. My setosa, pociloporas, digitatas, stags are mid level and all doing good. My bird's nests that are lower level bleached a bit. I started to increase intensity and it hurt them. May have been other factors too but I've also been thinking about lowering the intensity.

I'll have to check my program but no intensity stays the same over each 1 hour interval. All my zoas and palys are the bare bottom and doing well. Any brighter and my blue hornets don't open. Acclimation is obviously part of this whole process too. So many factors. Surface agitation clarity and nutrient level in the water. Etc.

Moons 9am-1am (ch3) blues on at 12-12 (ch1) whites, reds, purples 2-8 (ch2). All ramp up then down... Still dialing in. The touchscreen controller is too fun!!! Love this light big time.

Glad to hear someone is having the exact same situation as me. Any higher light Zoas on bottom close. At current intensity monti digi 1/3 down not happy.

Yeah my tank is 21" tall so we are in the same boat on that angle. I also got some dragons breath algae growing nice on a few plugs. I'm just blown away with the colors and how much nicer they are. My fish and zoas are so colorific and it changes every hour. :lolspin:
