    Thanks for bringing this to our attention.

    The dosage based on mass is correct.

    Dosing based on tsp is always an approximation based on the grain size and/or shape used to make the calibration. This will most likely be different than what you have. Probably dosage with tsp for these micronutrients were never calibrated and received a default value. Given their lack of accuracy and small conc. it's a bad idea to dose individual micronutrients to aquariums using tsp.

    The ml option is there for solutions not for solid salts. Far as I know this issue has already been discussed and will be corrected. Dosing solid salts based on volume defies logic in my opinion.
