Ok thanks. I will try to find some problem with my ingredients. Maybe adding and mixing a total of only 2 litres of RO water to the 7-1/4cups MAG & 3/4cups Epsom salts is too little. Perhaps I should be adding something way more. ie adding 2 gallons of RO? If not, then I must have received some impure chemicals.Many people have used the recipe, with a bit of precipitation. I've not seen anyone report a large amount.
