Corals dying

[hadams356]

I been having problem with corals dying. I have 200 g system, recent icp test shows low on some elements but way high on lithium. No metals shown.
I now have more dead corals in tank than live ones.
I looked for bugs haven't seen any.
Alk,Ca and Mag all within range. I been fighting the unknown for several months now.
Any suggestions appreciated.

what are your Nitrate and Phosphate levels>

I had a sea cucumber die in my tank a couple years ago... did bad things to it. I lost 1/2 my corals... I also had high Nit and Phos at the time. The GSP and xenia were the first to go believe it or not.

Do you do regular water changes?

System age?
Can you post the results of icp?
Cal, alk, ect "all in range" is really not helpful in detecting a problem. We really need facts.

Rusting magnet or defect heating element?

How are the corals doing today?

Yeah you do have something going on there. To have a Hollywood stunner dying back like that! I could frag mine with my shoe outside of the aquarium and throw pieces back in the aquarium and they would grow. Did someone clean around the aquarium? Did you release some pocket of sulfur and methane from a deep sand bed?

Did you anger that Sinularia?
