Contains no nitrate and does not contribute to algae growth
Phosphorus is one of the main three macro nutrients (nitrogen, phosphorous, potassium: NPK) required by plants and can often become the limiting factor to growth in a flourishing system. Flourish Phosphorus is a safe solution of potassium phosphate that takes the guess work out phosphate dosing.
Unlike competing products that mix nitrate and phosphate in a fixed ratio, Flourish Phosphorus (being nitrate free) allows you to dose phosphorus according to the needs of your plants without the risk of overdosing nitrates. Likewise, because Flourish Nitrogen is phosphate free you can use both products together to target exactly the ideal amounts of each for your system.
When used as directed Flourish Phosphorus will enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit use with Flourish Nitrogen and Flourish Potassium. Guaranteed Analysis: Available Phosphate (as P2O5) 0.3 percent, Soluble Potassium (as K2O) 0.1 percent, Derived from: Potassium phosphate
DIRECTIONS: BEGINNER: Use 0.5-1 mL (dispenser enclosed) for each 80L (20 gallons*) once or twice a week. EXPERT: The beginner dose raises phosphorus by 0.01 mg/L (0.03 mg/L phosphate). The ideal phosphate level will vary from system to system, but generally ranges from 0.03-1.0 mg/L Use MultiTest: Phosphate 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 For 2 & 4 L containers, 1 capful is 10 mL.

Seachem Flourish Phosphorous 500 mL
Seachem Flourish Phosphorus helps accelerate and enhance the growth of live aquarium plants, without contributing to nuisance algae growth. This simple, safe solution contains no nitrates, allowing precise phosphorus dosing to meet your plants' needs.
Flourish Phosphorus supplies an ideal concentration (4,500 mg/L) of phosphorus, one of the three macro nutrients required for healthy plant growth (the others are nitrogen and potassium). Unlike competing products, it is nitrate-free and allows you to accurately dose your aquarium's phosphate levels without the risk of overdosing nitrates. Use Flourish Phosphorus along with Flourish Nitrogen and Flourish Potassiumto achieve an ideal ratio of all three nutrients.
Beginner: Use 2.5 mL (half a cap) for each 80 L (20 gallons) once ot twice a week or as needed in response to signs of phosphorus deficiency (such as stunted growth and/or very dark green coloring).
Expert: The beginner dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate level will vary, but generally ranges from 0.15-1.0 mg/L. Use a reliable test kit 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: 0.8x20x0.1=1.6 mL.
