Never did figure out why. I figured it might be some trace element I was low on but didn't test. But if all of your other corals are thriving I wouldn't start adding random supplements. But either way you do want some nutrients in the tank. Nitrates right around 5 and phosphates around .03ish. If you don't have a low range Hannah Phosphorous checker you could be in the right range with phosphates but your test kit won't detect low range. If it's in the budget I would recommend getting a Hannah low range phosphorous checker. Make sure its the one that test in PPB.
