What’s the difference between Buffer Plus™ and Purple-Up™?

Both of these products contain the same main core ingredient:  Aragonite™ powder dissolved in water.  Aragonite™ contains Calcium and Carbonate in balanced proportion and is also a good source of Strontium, Magnesium and other minor trace elements.  This is the sole ingredient in Buffer Plus™, (which is the same as Aragamilk™).  This ingredient makes Buffer Plus™ the ideal alkalinity booster / calcium and trace element source.  Purple-Up™ expands on this main ingredient by adding an iodine source and adding an ionic form of calcium thus increasing the amount of available calcium.  This makes Purple-Up™ a more complete additive that may be used as a stand alone reef supplement.



Why would I want to use Purple-Up™ over Buffer Plus™, or vice versa?

Buffer Plus™ is a great buffer to keep your alkalinity in check and can be a good source of calcium and other trace elements.  Purple-Up™ has an iodine component as well as the aragonite component of B+. (See also preceding answer).
