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

Raises carbonate hardness (KH)
2000 meq/L (5600 dKH)
Add 30mL to 60L (15 US gallons) 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 ¼ to ½ 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.
