Unhappy Acan?

[Jordan Stone]

Hi, I recently made a change from a 28 gallon Biocube to a 40 Gallon Innovative Marine, I've been watching my corals acclimate, and noticed that one of my acans skeleton may be exposed? Can anyone help me identify this? Not sure what I'm looking at. I'm thinking too much flow or the new lighting with the Hydra 26.

salinity:1.024
calcium:445
alkalinity:8.4
nitrate:0
nitrite:0

Phosphate?

My acans did they same. Eventually they all died. I also had 0 nitrates and 0 phosphate. Also other lps died...

You're going to want to raise your nitrates a little, and it could be numerous other things like you mentioned, flow and lighting are big ones as well. What type of lighting was on your previous tank? Just the stock biocube LED?

Beautiful Acans BTW.

It was a custom LED (Steves LEDS) They specialize in custom Biocube lighting

To me it's looking like a lack of nitrates if that's the case(Steve's LED is a great light), how often do you feed your acans?

And did you match light intensities between the hydra and the steves LED?

It's hard to match the intensity, but I'm in acclimation mode and confirmed with BRS to to th T about if it's on the appropriate intensity. Phosphate is at .03 it looks like. In regards to the feeding they get fed a couple times a week a long with other coral.
