So I have been battling this issue of ALL my blue corals (SPS, LPS, Zoas) turning grey for long enough and I cant figure it out. Can anyone tell me why my blue corals have all turned grey?
All other colors seem to be good, not great, but better than decent. Purple is decent. I have tried Lugols thinking I was lacking Potassium iodide but after dosing 2-6 drops daily for months on end no change. When I dosed X amount of drops I would maintain that dosage for 2 weeks, currently dosing 2 drops daily. And even through dosing I never noticed any change. But I do not test for Iodide.
I also assumed that maybe it was a nutrient issue cause I dose vinegar but my N&P say otherwise. And I feed heavily enough to cure the world hunger issues.
Growth on corals has been really good, just the color blue eludes me.
My system setup:
100 gallon mixed reef with a ritteri anemone
2 X250 20K MH (lamps 3 months old) w/ 120watts of blue led 420nm-475nm
S.G. 1.026
Ca-420
Alk 8.0
Nitrate 3
Phosphate .05
Whats everyones thoughts
