    Bought a colt coral about 2 wks ago. About a wk ago the branches started to fall off. Tonight it has completely detached itself from the rock it was attached to. Wouldnit give off any smell if dying? Salinity 1.026, alk 5.4, ph 8.4, mag 1250, calcium 500. It was on the sand bed in a low flow spot. Lights are sufficient as I have mh. I know alk is low, working on raising.

    You really need to raise the alk slowly if that is the true value for alk, I am surprised you are not having more issues with that value. Colt corals in my experience do not like the intense lighting of MH, I have a few pieces hanging on since I changed to MH years ago but nothing like I had with other types of lighting,

    So it could be a lighting issue,

    No it's most likely the alk level stressing the coral. Me, I would correct that and move the corals to a shaded area.
