Sodium Carbonate 2Kg

Sodium Carbonate (Soda Ash) is used alone or in combination with Sodium Bicarbonate to maintain proper alkalinity and raise the pH of the aquarium water. Commonly used in the 2 Part daily dosing system to maintain proper calcium and alkalinity levels on a daily basis. We recommend testing alkalinity levels before use.  Dissolves crystal clear.

Using Sodium Carbonate

  • Pour 1.5 litres of with RO/DI or distilled water into an empty container.
  • While stirring water, add 1 level cup of Sodium Carbonate.
  • Increase amount at a rate of 1 level cup per 1.5 litres of water
  • Once dissolved, transfer solution to the dosing container.
  • Label Alkalinity and let sit before use.


If you have difficulty dissolving Sodium Carbonate in water float the container in a sink of hot water and stirring the solution.  Do not add Sodium Carbonate directly to the aquarium water. You should not raise alkalinity by more than 1 dKH (0.36 meq/l) per 24 hours.


Avoid contact with eyes, skin, and clothing. Wash hands after handling.
