I would like to prepare a mineral free diet using purified ingredients, but these purified ingredients contain some ash percentage as a contamination. Is there any way I can make a mineral free diet for fish?
Minerals aremicro nutrients and an important part of even fish diet.Though you want to remove from water ,in the diet in some or the other form it will be available for the fish. Atleast any one type of mineral will be surely.....
you want to keep this as a control and study? If so it would be quite expensive to provide only componant diet.
