Can anyone give me some advice on what to do with this guy. I cannot seem to get him happy. Have tried low flow low light, mod flow mod light, now trying high light mod flow. Parameters fine except alk and ca a little low...7 on the alk, 360 on ca. I have been worki g on bringing those up slowly. All other corals, sps, frogspawn, hammers, zoas, cabbage, doing fine. Rbta and long tentacle anemone fine as well. Pic attached.
