I don't have access to the full article, but I expect it is a very interesting read. I've highlighting some comments from the abstract that could be of interest:

The trace metal economy of the coral holobiont: supplies, demands and exchanges​

ABSTRACT
The juxtaposition of highly productive coral reef ecosystems in oligotrophic waters has spurred substantial interest and progress in our understanding of macronutrient uptake, exchange, and recycling among coral holobiont partners (host coral, dinoflagellate endosymbiont, endolithic algae, fungi, viruses, bacterial communities). By contrast, the contribution of trace metals to the physiological performance of the coral holobiont and, in turn, the functional ecology of reef-building corals remains unclear. The coral holobiont's trace metal economy is a network of supply, demand, and exchanges upheld by cross-kingdom symbiotic partnerships. Each partner has unique trace metal requirements that are central to their biochemical functions and the metabolic stability of the holobiont. Organismal homeostasis and the exchanges among partners determine the ability of the coral holobiont to adjust to fluctuating trace metal supplies in heterogeneous reef environments. This review details the requirements for trace metals in core biological processes and describes how metal exchanges among holobiont partners are key to sustaining complex nutritional symbioses in oligotrophic environments. Specifically, we discuss how trace metals contribute to partner compatibility, ability to cope with stress, and thereby to organismal fitness and distribution. Beyond holobiont trace metal cycling, we outline how the dynamic nature of the availability of environmental trace metal supplies can be influenced by a variability of abiotic factors (e.g. temperature, light, pH, etc.). Climate change will have profound consequences on the availability of trace metals and further intensify the myriad stressors that influence coral survival. Lastly, we suggest future research directions necessary for understanding the impacts of trace metals on the coral holobiont symbioses spanning subcellular to organismal levels, which will inform nutrient cycling in coral ecosystems more broadly. Collectively, this cross-scale elucidation of the role of trace metals for the coral holobiont will allow us to improve forecasts of future coral reef function.

Thank you for sharing, I'll be reading shortly!

So I was trying to find the article through my college library and of course I couldn’t but I found others that talk about trace metals and corals

 

[Reefing_addiction]

From the abstracts I read it looks as though we really should be dosing certain trace metals to our tank…..problem here is the ability to test and get accurate results

Everyone does add all trace elements in foods, and those who do water changes also add some that way.

Yes but is it enough? There is that whole moonshine method

Yes but is it enough? There is that whole moonshine method

Well, that's the premise of every trace element supplement by every company, and it is easy enough for any individual to experiment.
