Potassium Bicarbonate

2Hr Aquarist Commentary: For increasing KH levels without increasing GH, use Potassium Bicarbonate or Nilocg's KH booster. Increasing carbonate hardness/alkalinity increases the pH of the water. This is done more for livestock than plants as most plants grow better in soft water rather than hard water. (Exceptions being Pogostemon helferi, Valisneria species).
