25kg Aquastab Limestone/Calcite Pellets
Aquastab is natural limestone or Calcium carbonate and is a natural way of elevating the pH and alkalinity of slightly acidic or soft water.
Most ground and surface water in the Western Cape is mildly corrosive to metals and or concrete. Rainwater is also soft and therefore corrosive.
Mineral deficient water will naturally absorb minerals when in contact with limestone.
Aquastab is recommended for treating water with relatively low iron and manganese content and >6 pH. Calcite is a harder form of calcium carbonate which dissolves less readily than limestone. Alternative products and methods of stabilisation should be used for more aggressive waters. Iron rich waters should first be treated through an iron removal filter.
