Ah, sorry having re-read what you wrote you are making a concentrate so it’s 10ml to be added to 4990ml….with 100ml of concentrate to make.
RE Magnesium Citrate. Not sure. Some people say Calcium citrate tastes bad, others report nothing bad about the taste but rapid bacterial growth in water promoted by citrates. Citrates will contribute to alkalinity too, so that needs to be calculated at least. You could try it, just depends on whether or not the Magnesium citrate capsules contain only Magnesium citrate or if they also contain preservatives or other things. You need to know the form the Magnesium Citrate takes too e.g if it is trimagnesium citrate or magnesium citrate…or maybe something else.
