90G tank with 100lbs or so of live rock. 7 months old.
I have a few things that don’t look quite right.
I noticed my Duncan not opening and then 2 colonies of star gazer zoas plus some other random colony on a rock. They just don’t seem happy. I have 40* other zoas, euphyllias, pipe organ, ricordia that seem very happy.
Temp 78
Mg 1250
Salinity 1.025
Alk 8:5
ph 8.1
Phosphate 0.2
Nitrate (2nd from bottom on card). Think that 2
I suspect maybe over feeding a high nitrates so doing a water change, cleaning the skimmer and feeding less. No algae breakouts.
What’s interesting is the 2 star gazer colonies are in different parts of the tank and they look the same and not happy. I wonder if particular types of zoas are more susceptible than others and these are my canaries in a coal mine.
