Im scratching my head still. With the triton dosing system, all we can do is follow the alk level and hope all other params fall into place. I feel one if the components must have been off.

I suspect that at least one of the solutions is a mix of various trace elements. I'd be cautious with the trace elements solutions. It'd be strange if the calcium and alkalinity solutions were causing trouble, but certainly not impossible.
Thank you Bertoni. Yes, I will not mess with trace elements again. I certainly think something in my water is way off for the sps.

Hope you can find what's happen so we all can learn with it.
Agree alfareef. I tried some of the AF drops maybe 6 months ago and didnt like the results either. With the Core 7 however, the bad reaction was almost immediate. I was very cautious to keep the tank stable during the new dosing implementation.

Here is the tank before the start when corals were doing fine
