Here's a more detailed analysis of the results and how I decided not to dose anything else beyond the Kalkwasser with vinegar. I was considering using the Red Sea Colors program.
Part A of the program includes: I2 | Br2 | F2
The ICP indicates that the Iodine is low, but not depleted. On the other hand Br is slightly elevated. It doesn't test Fluoride.
I conclude that there's no need for this part of the program.
Part B includes Potassium and Boron.
The ICP test reported K within normal range and Boron almost within normal range.
Part C includes iron, manganese, cobalt, copper, aluminum, zinc, chrome and nickel.
The ICP test reported most of these elements either very low or below detectable levels.
Part D of the program includes a blend of 18 elements that according to the ICP test are mostly within normal values.
Given these results I decided not to dose anything more beyond the Kalkwasser/vinegar.
I will probably do another test next year.
