Mass STN of Acros

Have you thought of using KZ flatworm stop? It will strengthen all corals even if there are no bugs. Run it for 6 months.
I have used it the past when observing stn at the base. The stn was caused from disco mushrooms releasing and floating around the tank stinging everything they touch.
It stopped the stn and most corals survived unless the disco landed on said coral and was their for some time.
In my 20g reboot I went from 16hds and xr15 blues to a 250 watt halide. No stn but
The blue and purple stags are coloring up now after 2 months at 5hrs peak halide. I use a 16hd for up/down and color.

Exactly what I’m doing with my radions… my Cali and miyagi tort are very deep and rich blues and purples with the halides and I never got that before. My radions are on for 12 hours a day and at noon my halides kick on for 4 hours.
Yea my Oregon tort is very dark blue under halides. Its a much lighter blue under the Radions and 16's.
Their is something missing in the leds that halides give.
With that some corals under the 15's&16's have color that halides cant give. Thats because of the adjustability of the leds.
I am still in the led learning phase.
With that, except for the 20g which is a 1 year project, I am 100% led and dont anticipate going back.
Corals grow just as well as my halide systems did. Color can be adjusted with supplemental blues.
I ran 2 Orphek blue bars on my 120. The halides provide the power and the blues were used for dawn dusk viewing.
I'm not sure what the mystery is here. Nitrates and Phosphates low but detectable and 400 PAR, low Dkh, well there's your issue.
Unless you have excellent flow and a high nutrient system, Acros will do just what you're experiencing. The Alk is dangerously low in my experience and opinion. You're providing corals with high energy (400 PAR) , but giving them no fuel (nitrates, phosphates, etc) .
Chemistry 101.

It does not need to be. People want faster growth so they elevated it.
People used to run alk at 15-18 years ago.
I run my alk at 6.5-7.5 target 7.
My corals grow just fine at close to NSW levels.
My take over the years is if its good enough for the ocean then we should try to make it as close as we can get.
You're never going to replicate the ocean, in any form. Trying to get exact ocean parameters is futile as we don't have the volume that the ocean does. Out alkalinity dissipates over the course of the day as it's used by corals. The ocean has an unlimited supply that never changes.
Regardless of where you want to keep alkalinity, that isn't the OP problem. Lack of nutrients in a high energy situation is his problem. Exacerbated by the drastic lighting change with no par meter to match par from before.
But our aquariums are not the ocean... in fact they are vastly different and sometimes what works there does not work well here.
