- Algae Control: Formulated to accelerate healthy plant growth without fueling unwanted algae when used as directed.
- Invertebrate Safe: Safe to use in aquariums containing shrimp and other sensitive invertebrates.
- Part of NPK System: Designed to work alongside Seachem Flourish Nitrogen and Flourish Potassium.
Dosage & Directions
- Beginner Dose: Use 2.5 mL (about half a capful) for each 80 L (20 US gallons) once or twice a week, or as needed for deficiency signs (like dark green leaves or stunted growth). [1]
- Expert Target Dosing: The beginner dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate). Aim for a general target range of 0.15–1.0 mg/L phosphate.
