Potassium-based, sodium-free alkalinity blend.  Increases potassium and alkalinity in recirculating seawater systems, as well as pH to a maximum value of 9.20. Formulation excludes phosphate- and hydroxide-based salts.  Apply in systems with deficient K and elevated Cl and Na as a means of increasing K and alkalinity without adding Cl or Na; this formulation is particularly suitable for application in recirculating marine ecosystems which utilize chloride-based Ca and Mg supplementation in conjunction with sodium-based alkalizing compounds, and in which water changes are not made with adequate frequency to prevent imbalance of major ionic ratios from occurring.
1 mL Carbon8 K per 26.4 gallons (100 L) increases alkalinity by 0.1 dKH and [K+] by 0.90 mg/L. 160,000 ppm total carbonate species; 89,965 mg/L potassium.  Active components: USP-grade potassium salts of bicarbonate, carbonate, and borate.
