The phosphate was 0.04-0.09 just realized it was wrong in the original post. I actually moved them to a tank of just anemones. although it’s mixed with high phosphates (too high for Hanna) they have survived and come back from the bleaching. Thanks to all who gave info, I think my sps display is just not cut out for nems. I suspect it is something bacterial I have also used cipro on the tank with little to no results.
You can see yellow of the colorados tucked in the middle. They are now in higher phosphate and nitrate, with low alk. They came from a dirty tank so maybe they just like dirty tanks
