Beginners
2.5 ml (half cap) per 80 L (20 US gal) once or twice a week or as needed in response to signs of phosphorus deficiency (e.g. stunted growth, dark green plant).

expert:
The starter dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate level will vary, but generally ranges from 0.15 to 1.0 mg/L.

To target a specific phosphate increase, dose according to the following equation: 0.8vp=m, where v=tank volume in gallons, p=desired phosphate increase and m=volume of product to be used in milliliters. For example, to raise 20 gallons to 0.1 mg/L of phosphate, you would use: 0.8*20*0.1=1.6 mL.
