Just wondering at what point the calcium level is too high for coral (or fish). I only have some Zoas, Shrooms, and a Kenya (in additiona to my fish), but I intend to add more coral. My calcium was optimal for the longest time, but I recently upgraded my tank, and when I tested the water a few days later the calcium was at least 520. Should I be concerned? The Zoa and Kenya don't seem happy, not really opening up, though the shroom is living large.
Thanks in advance for the input!
