ICP Tissue necrosis

[mandarins]

Hi everyone ,

I was wondering if I could get some help interpreting my recent ICP results. One torch coral sloughed off all its flesh practically overnight. Other corals look fine but not as much polyp extension. Should I harvest some macro algae from the refuguim to raise nitrates?

Is there anyway to raise nitrates without raising phosphates?

Stats: 35 gal DT with 20 gal sump, UV sterilizer, filter socks, ATO that I think is lowering my salinity too much

Your copper and aluminium are extremely high, more importantly than raising nitrate at this point would be to look for the cause of this. I’d start by checking pumps, wave makers etc…

I would look at your RODI system. The high zinc there might be driving the tank zinc up.
