Flourish Phos-phor is a safe solution (4500 mg/L of phosphate) from potassium phosphate that takes the guesswork out of measuring phosphate doses.

Key features:

• Phos-phor supplement for planted aquariums
• A safe solution containing 4500 mg/L of potassium phosphate
• Takes the guesswork out of measuring phosphate doses

Instructions for use:
For beginners
Use 2.5 ml (half a cap) per 80 liters (20 US gallons) once or twice a week or as needed in response to signs of phosphate deficiency (e.g., stunted growth, dark green plant color).

For professionals:
The beginner dose raises phosphate levels by 0.05 mg/L (0.15 mg/L of phosphate). The ideal phosphate level will vary, but it typically ranges between 0.15-1.0 mg/L.

To achieve a specific increase in phosphate levels, dose according to the following formula: 0.8vp=m, where v=volume of the tank in gallons, p=desired increase in phosphate, and m=volume of product used in ml. For example, to raise 20 gallons to 0.1 mg/L of phosphate, you will need: 0.8*20*0.1=1.6 ml.
