500g Calcium Carbonate
Otherwise known as Chalk, this product is used to adjust water pH. Calcium Carbonate will raise water pH.
It has very limited solubility and is only effective when added directly to the mash. Use for making dark beers in areas of soft water. To monitor pH in the mash use test papers (product K1163) or a electronic pH meter (product WI29612 or WQ1199) to help determine how much to add.
