Anyone know what happened to my duncan? Two of the polyps look torn apart I believe there are no predatoty pests as I used dry rock and all corals were dipped. Tank has had corals in fo 5 days. There was a small wavemaker pointed at it, could it be too much flow that caused this?

OK, I have my parameters going well or at least going in the right direction.
After all that. what distroyed my Duncans was my own lack of knowlege
I have been told that I put the Duncans too high in the tank and too close to the light, bottom line is I burnt them, the analogy with a Red headed white skinned person with freckles sunbaking for 3 hours at the beachin Australia in mid summer.
I have been heavily researching lighting and the recommended lighting for each coral species taking into account what light they were aclimated to before I buy them where possible.
I do not feel good about my ignorance...........so much to learn;)

Salinity range- 1.024-1.025
Oh range - 8.0-8.3
Temperature range 77-79
Moderate light and water flow keeps them happy
