Any tips on why a millepora might close up and start to go pale when the rest of my sps are doing good? I've got two milles (red arrows in pic) that have no polyp extension and look like they might be dying. They are mounted high under ecotech radions. Meanwhile all my other stylos and acros are just fine and have good polyp extension and color. I have another mille nearby which has good PE but is developing a concerning white spot (blue arrow). I've got Calcium:440, dkh 9.6, salinity 1.025, temp 82.6F, very low phosphates/nitrates. Anyone else seen this type of situation or have any suggestions?
