My zoas haven't opened up in about a week or so, although my palys seem fine. I have 7 dif kinds of zoas spread throughout 4 different colonies. The largest having several palys scattered throughout it, which have remained open. My sg went high on me due to some equipment failures and was at about 1.030. Over several days I slowly brought it back down to 1.025 by supplementing saltwater with rodi water. All my water parameters seem ok; ph 8.2, nitrates 0, nitrites 0, phos 0, calcium 400 and mag 1200. Water flow hasn't changed nor has the lighting, however I did recently add some chaeto to a newly setup refugium, which lighting cycle runs opposite of display lighting to keep ph from changing much. Any thoughts on what could be keeping the zoas closed? It all started with the sg spike, is it possible that they just haven't recovered yet? Btw I have done a freshwater rodi dip with the zoas and cleaned them off with a turkey baster regularly also.
