Calcite chips for raising pH 

G3000 is very pure white calcite chips used to increase the pH of borehole water and other acidic waters in an efficient and cost-effective manner. The chip size is 2-3mm.

Calcite is a harmless natural mineral that comes from the ground. It is commonly used as a source of calcium for plants, animals and humans. The process route for G3000 is mining, milling and classification. No chemicals or harmful substances are used in its production.  

In the presence of acidic water G3000 partially dissolves, neutralizing the water and rendering it much less corrosive to pipes and plumbing. It is only reactive in the presence of acid. In neutral or alkaline environments, it is inactive and insoluble. So once the water is neutral, G3000 becomes inactive and the water remains neutral.


  • high surface area means fast neutralization of acid
  • Non-toxic
  • Harmless to humans, plants and animals
  • Unlike lime or caustic, it does not burn the skin
  • It is easy and safe to handle
  • Cost-effective compared to other pH neutralizers
  • Cannot be over-dosed 
  • Available in 30 kg bags and 1kg packs
