Aquavitro Carbonate 350ml

Carbonate hardness, (KH), is a measure of the bicarbonate and carbonate content of the water. Carbonate hardenss contributes to pH stability and can also act as a CO2 backup reserve if CO2 levels fall too low.

Carbonate is derived from potassium bicarbonate. It increases both carbonate hardness and potassium. The concentration of carbonate is 2000meq/L (5600 dKH). In addition, it contains 78,300 mg/L potassium.

Add 49 mL (one full cap) to 25 US gallons (95 L) of water once a week (or as needed). This dose raises carbonate hardness by 1 meq/L (2.8 dKH). For unbuffered water or in the absence of CO2 injection, use 1/4 to 1/2 dose to avoid impacting pH.

Plant preferences vary, but a good rule of thumb is about 1-2 meq/L (3-6 dKH). This dose increases potassium by 40 mg/L.
