Chronicles of a 20 (Bulkhead cracked!!!!!)

I am still in a similar situation as I have been for the past 7-8 months; no growth.

I just can't seem to pin-down what I need to do to get things corrected.

Salinity: 1.025
Phosphate: 0.06
Nitrate: 0
Temp: 76 degrees
calc: 450 ppm
Mag: 1480 ppm
Alk.: 3.6 meq/l

I have had a little improvement in color since I started dosing amino acid and oyster eggs, but growth is still absent.

Zoas don't grow, mushrooms rarely grow (6 in new mushrooms in 12 months) and Coralline has stopped growing and started to disappear.

All of my SPS have encrusted a little bit, but they always seem to stop after covering the super glue.

I am beyond frustrated. I had good growth for a short period of time from November to December where everything I had grew and grew quickly.

I just don't get it. Coralline, zoas and mushrooms should grow like weeds; same with monti caps. Mine don't grow at all. Candy Canes don't grow anymore either.

Everything looks great and healthy.

Very strange situation. Maybe I have too much light.
