Flourish
Recommended Dosage: Use 1 capful (5 ml) for each 250 L (60 gallons*) once or twice a week. For smaller doses, please note that each cap thread is approximately 1 ml. Refrigerate after opening. Use only in contained aquaria as directed. This product is not intended for natural bodies of water or agricultural use.

Flourish Iron
Recommended Dosage: Use 1 capful (5 ml) for each 200 L (50 gallons*) or as required to maintain about 0.10 mg/L iron. For smaller doses, please note that each cap thread is approximately 1 ml. Use Seachem's MultiTest: Iron^TM test kit (#434288) to monitor iron concentrations. Use as needed to combat signs of iron deficiency (usually seen in new growth), which include: chlorosis (yellowing) of tissue between veins and short and slendor stems.

*1.0% Soluble Iron (Fe)
Derived from: Ferrous Gluconate

Flourish Excel
Recommended Dosage: On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 gallons*). Thereafter, use 1 capful for every 200 L (50 gallons*) daily or every other day. Dosing may be slowly increased in high-growth aquariums. For smaller dosing, please note that each cap thread is approximately 1 mL. Do not overdose.

Flourish Enhancer Kit

Flourish Nitrogen
Recommended Dosage:
Beginner: Use 2.5 mL (half a cap) for each 160 L (40 gallons*) twice a week or as needed in response to signs of nitrogen deficiency (e.g. stunted growth, chlorosis). For smaller doses, please note that each cap thread is approximately 1 mL.

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.

*1.5% Soluble Nitrogen
Derived from: potassium nitrate, urea (iminium salt)

Flourish Phosphorous
Recommended Dosage:
Beginner: Use 2.5 mL (half a cap) for each 80 L (20 gallons*) once or twice a week or as needed in response to signs of phosphorous deficiency (e.g. stunted growth, plant dark green).

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: Phosphate^TM 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 Phosphate

Flourish Potassium
Recommended Dosage: Use 1 capful (5 mL) for every 125 L (30 gallons*). This dose raises potassium by 2 mg/L. Repeat 2-3 times per week or as needed (in response to signs of potassium deficiency in older leaves which includes: chlorosis (yellowing), necrosis (death/browning), and weak stems and roots.

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.
