Some time ago I've decided to start making my own trace elements and have started with Iodine, Molybdenum, Strontium and Manganese. Today I have received all elements I needed to make these solutions in line with the help I got in the forum.

I have been using a well known ICP/Dosing method brand for the last few months and would like your help to validate my "maths/assumptions" to calculate the concentrations of each trace element. The idea is to make my solutions with the same concentration of this brand (not naming them deliberately) to allow me to continue to dose the same amounts they recommend without any calculations!

So for Iodine:

If I am told that the last analysis was 51 µg/l and the reference is 60 µg/l and my tank net water volume is 750l it means that I am lacking 6.75mg of Iodine for the whole 750l of water. Am I assuming correct?

Also, if the recommendation is to dose 1.35ml of their solution, does that mean that such solution would have a concentration of 5mg/ml or 5g/l?

Molybdenum:

The analysis was 5.935 µg/l and the reference is 12 µg/l for the same 750l means that I am lacking 4.545mg for the whole 750l of water.

The recommendation is to dose 45.45ml of their solution, does that mean that such solution would have a concentration of 0.1mg/ml or 0.1g/l?

Strontium:

The analysis was 7.017 mg/l and the reference is 8 mg/l means that I am lacking 0.735g for the whole 750l of water.

The recommendation is to dose 91.88 ml of their solution, does that mean that such solution would have a concentration of 8mg/ml or 8g/l?

Manganese:

The analysis was 1.33 µg/l and the reference is 2 µg/l means that I am lacking 0.503mg for the whole 750l of water.

The recommendation is to dose 5.03 ml of their solution, does that mean that such solution would have a concentration of 0.1mg/ml or 0.1g/l?

Thanks a lot and good reefing!
