Ive been struggling with my biocube for quite some time. Between dinos and corals slowly dying off ive taken a step back the last month and was hoping a more hands off approach may help but things seem to be worse. I did maintain testing 2x a week and nothing seems alarming. Alk is allways between 9-9.2 cal had been steady around 460 ph 8.3-8.4. Nitrites 5-10 i cant figure this out and im in the process of moving. For the last few months ive lost several corals and the rest are not looking great yet some still entrusting like crazy. My last icp showed iron at 7ppm but nothing else out of the green zones.
