Hi Bob,

I'm wondering if you could provide some insight on adding these two elements to a reef tank. I have been experiencing some tissue loss and poor coloration in several LPS lately and am wondering if a deficiency in these may be the culprit. There are my thoughts:

  1. I previously dosed these in the form of Two Little Fishies Iron and a few months after stopping the symptoms developed
  2. Information on Mn supplementation in The Reef Aquarium Vol 3.
  3. I am suspicious that my two large Tridacna clams may be more efficient at sequestering Mn and therefore the LPS are suffering.


Please provide any info you can share on these elements... especially a DIY formula (if there is one).

Thanks,
Tom
