PDV food grade salt is a fine flowing salt and is as pure as it gets.
There are many uses for this grade – it is actually the grade used to produce tablet and block salt.
Some people choose this food grade for their Koi fish. You do not need to specify the food grade version for them but if you do, you won’t see any difference to the non-food grade except in the bag colour and the price.
