Hey, I bought a colony of Waving Xenia at my local fish store for a steal, and I got it as a filler for my new reef tank. However, a fourth of it opened up the next day, but then after that, nothing opened. I have done a water change, changed the lights and turned them down, added a powerhead, and changed the current to an offset around the rocks. I also have a frag of Pulsing Xenia that is opened and have done better with my changes as well as Green Star Polyp and Winter Star Organ. My parameters are Calcium: 420, ALK: 15, Phos: .25, Nitrate: 10, Nitrite: 0, Amo: less than .25, Salinity: 1.028, Temp: 78, pH: 8.2. Now I have been slowly doing water changes over the past few weeks and lowering my ALK down to the range, due to using in house RO water to start up the tank and that was the wrong decision. But, I don't think that's the problem with my other corals doing fine. Going to upload a picture of the location of it and my light settings for any tips cuz I wanna see it open up and thrive.
