How long for sps to colour up after nitrate accident

[Dinodanger]

i knocked over the potassium nitrate and the tank went from near 0 nitrate to 25ppm the sps didn’t bleach but colours are slightly duller compared to before, I’m using a refugium to lower nitrate, when can i expect acros to regain colour ?
phosphate at 0.03 or slight under

Far too many variables to be able to give a good answer. Best I can say is - it depends...

There is probably more info needed

Dude i overdosed nitrate to 40ppm and it literally took a year for my tank to even start to show signs of progress.
I lost a lot of high end and hardy corals from that. Never again....
Corals finally stopped dying and the ones that survived are coloring back up.

Ime, .02 phosphate with near undetectable nitrates has been the winning ticket for nutrient stability for me. Maybe 1-2ppm nitrate max...
