Reef Blueprint Isol8:B Boron Supplement for CoralBoron solution 44,500 ppm. Increases boron in recirculating seawater systems. 1 mL Isol8 B per 26.4 gallons (100 L) increases boron by 0.445 ppm. 5 mL Isol8 B per 20.0 gallons (75.7 L) increases boron by 2.94 ppm. 44,500 ppm boron, derived from borate salts of potassium and/or sodium (hydrated source, USP).Characteristics:Regular application intensifies red pigmentation and improves pH stability. Active Components: Potassium tetraborate, hydrated, USP.Basic Application: 1 mL per 26.4 gallons (100 L) increases [B] by 1.00 ppm. 5 mL per 20.0 gallons (75.7 L) increases [B] by 6.61 ppm. Reference Standard [B]: 4.45 ppm (S=35.0) 5.15 ppm (S=40.0) In established systems, increase [B] up to 5% of existing ionic value daily, until desired value or reference standard is reached.Size: 355mL
