Sps bleaching

FishOkay · Jun 4, 2022

All the sps in my tank seem to be slowly bleaching! I'm not sure what it is. I have a suspicion it was too much light so I have reduced the whites but I'm not sure. I have done an icp test but am waiting for the results.
The parameters I can test for are stable.

Cal; 450
Mag; 1600
Phosphate; 0.08
Nitrate; 7
Salinity and temp are stable 1.025 and 26 degrees but drops to its lowest of 25 overnight usually.

My last icp results about a month a go was good and there wasn't anything out of the ordinary.

IME, coral go brown if it’s due to too much whites (Usually signifying not enough PAR which usually comes from the blues).

Well I can see with the green digitata usually its like growth tips were white but now are brown. I mean I should have plenty of par without whites I have 2x kessil a500x over 3ft cube.
