Resurrecting this thread, I really appreciate the work. Based on the few that made the cut, in my opinion, I've started testing some of these and a couple others using ICP-MS from Oceamo to get a more accurate measure of some of the minute trace elements that won't show up on ICP-OES testing. I'm also incorporating test results from others that have sent samples in to Oceamo, as well. So far, I have two tests for Tropic Marin Pro Reef, one for Nyos, and one for Red Sea Blue Bucket. On the wish list are Aqua Forest Hybrid Pro and Fauna Marin but any are welcome.
I would have liked to run ICP-MS but it was far less popular and MUCH more expenisve. On the super low end levels, I highly doubt any company is "controlling" them in any manner. The majority are coming in as "impurities" with other source materials.
