What parameters make gold torches look duller? Photoperio, intensity, color spectrum, nutrient levels?

[JJKK]

Hi. I am trying to figure out how to get the gold and yellow back on some of my indo golds and an ASD HG. I have 3 XR30 Gen 4 Pro running CoralLab AB+ for LPS and have 4 T5s(2 Blue+, Coral +, and Purple) over a 5 feet tank. Light fixture is about 12" from the water line.

Over 2 months, I have noticed that some of my indo golds(NY Knicks) and ASD HG have gotten more purple or duller in color. I am trying to get them to color back up and I am wondering what to change?

Nutrients
.08-.12 Phosphate and 15-20PPM Nitrate: I think these are within range but may impact coloration based on photoperiods

Photoperiod
Was 15 hr from 7:30 to 10:30 for LEDs and 5 hr of T5s. 2 weeks ago, I already starting to shorten to 11 hour for LEDs with 3.5 hr of T5s

Par
Torches getting around 150-200 PAR. I have seen recommendations for HG to 350 PAR, so I am not sure if I am out of bounce here either. I could ramp up intensity more if needed. I max out at 65% on LED for 4 hours in conjunction with the T5s.

Color Spectrum
CoralLab AB+ schedule for LPS. 2 hr ramp to peak. Peak for 4 hr. Ramp down with All Blues for 3 hr and then deep blue ramp down for 2.5 hr.

So, those are things that I am looking to tweak to get the gold/yellow back for my torches. Please let me know what you have done to recover the colors in your torches. Thanks.

What do you mean by ab+ for lps? I have g5 x30 and only have ab+ setting not able to choose lps or sps within it.

What do you mean by ab+ for lps? I have g5 x30 and only have ab+ setting not able to choose lps or sps within it.

Take a look at the CoralLab Report's page 7: CoralLab Lighting Report

The White, Green and Red settings are slightly different from the SPS AB+ settings. I use Neptune APEX Fusion with XR30 Gen 4 Pros, so I have to enter these in myself.
