Hello!
I have a 14 month old 190 gallon sps dominant reef. I run a skimmer and have a healthy macro algae refugium. I run 2 AP700s. The tank has 7 fish. I feed daily. No carbon, no GFO.
In the last month, some of my sps, particularly my tri-color acros, have become pale. Polyp extension has become stunted. That said, they appear to be growing like crazy at their bases.
Parameters -
dKH (Hanna): 8
Ca (Hanna): 480
Mg (Nyos): 1350
NO3 (Nyos & Salifert): <1
PO4 (Hanna & Nyos): .01
SG (refractometer): 1.025
I figured the issue could be the low nutrients levels, so I began feeding more. Increased feeding has my PO4 around .08, and it will continue to climb if I feed more. However, no matter how much I feed, my nitrate doesn't move at all.
How can I increase my nutrients if......I can't increase my nutrients?
Separately, is it possible that the stunted PE and the pale coloring is related to the skeletal growth, and not a nutrient issue at all?
Thanks for taking your time read through this!
