Expert: The beginner dose raises nitrogen by the same degree that 1 mg/L nitrate would. This dose is sufficient to provide approximately 4 g of growth (dry) or about 20 g (hydrated) over a 1 month period (assuming all other necessary nutrients are provided). For increased growth, use proportionately more. To target a specific nitrogen increase, dose according to the following formula: 0.25vn=m, where v= volume of tank in gallons*, n=desired nitrogen increase (if using a "nitrate equivalent" value for "n" then use a factor of 0.05 instead of 0.25 in the formula) and m=volume of product to use in mL. For example, to raise 20 gallons* by 0.20 mg/L nitrogen, you would use: 0.25*20*0.20=1 mL.
Because one-half of the nitrogen in Flourish Nitrogen™ is from nitrate you can get a reasonable estimate of nitrogen levels by doubling a nitrate reading.

Expert: The beginner dose raises phosphorous by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate level will vary, but generally ranges from 0.15-1.0 mg/L. Use Seachem's MultiTest: PhosphateTM test kit (#901377) to monitor phosphate levels. To target a specific phosphate increase, dose according to the following formula: 0.8vp=m, where v= volume of tank in gallons*, p=desired phosphate increase and m=volume of product to use in mL. For example to raise 20 gallons* to 0.1 mg/L phosphate you would use: 0.8*20*0.1=1.6 mL.

Derived from: Potassium Sulfate
Elemental potassium is present at a concentration of 50,000 ppm (e.g 5%). Archaic fertilizer laws require us to list potassium in terms of equivalence to a material that is not present (K2O) rather than the more scientifically sound method of simple elemental equivalence.
