Assistance/Recommendations with SPS Placement

[Rudzbrewski]

I have been trying to get all my corals placed to remove the frag racks for the time being and because come are starting to outgrow the plugs. The main issue I keep running into is with SPS placement (milli, acro, humulis, etc). They often start getting white on the tips, display signs of tissue damage/distress, and have decreased polyp extension. Frag rack is always raised to at least the level of placement in the tank and even to the area as close as possible over time.

Luckily they have rebounded nicely when moved back to the frag rack in the past. I’m trying to figure out if it is light, flow, or CUC causing the lack of success with placement. My only plan at this point is to keep moving them back to the frag rack for some time to recover then try different spots in trial and error.

Open to any suggestions, thoughts, or recommendations.

I don't have a high conviction responses but something you could check into would be differences in PAR in particular, and possibly flow.

What is your light source(s), power settings, and height off the water? LEDs can create hot/cold spots that a PAR meter can reveal. I was shocked to find my old LED setup had huge PAR swings along the same horizontal plane.

Describe or picture also your powerheads/flow. My aquascape certainly has areas of less flow than my frag rack enjoys.
