Reef Blueprint Isol8:Co Cobalt Supplement for CoralCobalt solution 1,000 ppm. Increases cobalt in recirculating seawater systems. Increases primary productivity. Required by photoautotrophs (including zooxanthellae) for photosynthesis, and pigment, vitamin, and enzyme production. 1 drop (0.05 mL) per 7,472 gal. (28,281 L), once daily to maintain NSW value for S=35. 1,000 ppm cobalt, derived from cobalt chloride (hydrated source, USP).Characteristics: Provides cobalt, required by photoautotrophs (including zooxanthellae) for critical cellular functions, including: photosynthesis; production of pigments, vitamins, and enzymes. Critical for photosynthetic processes and nutrient reduction in systems employing algal turf scrubber filtration. Improves color intensity of zooxanthellate invertebrates. Aids in the reduction of nitrate. Active Components: Cobalt chloride, hydrated, USP.Basic Application: Dilute 1 drop (0.05 mL) Isol8 Co in 100 mL of purified water, and dose 1 mL of this solution per 75 gallons (284 L) daily. Label and date solution, and keep tightly-capped when not in use. Uncontaminated solution will remain viable for ≥2 years. Reference Standard [Co]: 1.77x10-6 ppm (S=35.0)In established systems, increase [Co] up to 5% of existing ionic value daily, until desired value or reference standard is reached.Size: 60mL
