    Is this calculator up to date and does it work for the pps pro from green leaf aquariums? Also for the micros section I chose cam+b but is ask me to also add in asorbic acid .015g and potassium sorbate .006g. Is that necessary? If so where do I get it from?

      Ascorbic acid is the antioxidant E330. In my country I can get it in grocery store in small packs, it’s used for baking and cakes. Another name is Vitamin C. About another I’m not shure. Hope it helps.
