Kenya's not doing well

[Mactoddy]

This is a bit of a puzzle. I have in my 90 gal. Two Kenya trees that are not doing well. They stay closed up a lot and when they are open up its just a little. My Kenya downstairs in my in my 30 gal. are looking amazing. Water parameters in both tanks are almost the same. My 90 is .03 phosphate and 10 nitrates. My phosphates are .01 and Nitrates are 2. I've heard that Kenya's are hard to get rid of. Mine are certainly not thriving. Thoughts or suggestions?

They are commonly used as a tester coral. Very hardy corals but sensitive to abnormalities in the water. If they are closed its because something is off. Usually nothing a water change won't fix. So do a pwc and hope for the best.
