Seachem Flourish Potassium provides concentrated potassium to support vigorous growth in aquariums with natural, living plants. This safe, effective supplement helps you avoid potassium depletion, yellowing leaves, and limited plant growth.

• Potassium supplement for the planted aquarium
• Helps maintain a vigorous level of plant growth
• Helps resolve yellowing, death/browning and weak stems and roots

Flourish Potassium contains 50,000 mg/L of potassium - one of the highest concentrations available. Water with low mineral content or systems with rapidly growing live plants can quickly deplete available potassium, causing potassium to become the limiting factor for further growth. Use Flourish Potassium to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.

Potassium is most easily obtained from potassium nitrate and potassium phosphate, both of which add either nitrogen or phosphorus to the water and make it more difficult to maintain a specific NPK ratio. However, Flourish Potassium is derived from potassium sulfate, which lets you adjust potassium levels without affecting your tanks nitrogen or phosphorus.

Directions: 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).

• Phosphorus supplement for the planted aquarium
• Safe solution (4,500 mg/L) of potassium phosphate
• Contains no nitrate and does not contribute to algae growth

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 aquariums 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.

Directions:
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.

Seachem Flourish Trace supplies a broad range of necessary trace elements for proper health and growth of live aquarium plants. Trace elements are normally depleted by utilization, oxidation and precipitation and are important to replenish on a regular basis.

• Restores trace elements on a regular basis
• Resolves a wide variety of visible plant problems
• Supplies a broad range of trace elements for proper plant health and growth

Oxidation and precipitation occur more rapidly with trace elements than with other micronutrients, making it important to restore trace elements on a regular basis. Flourish Trace may be used alone or in conjunction with Seachem Flourish for best results. By providing trace elements separately from essential minerals, you are able to replenish trace elements more frequently without unnecessary build-up of components that are used more slowly.

Signs of trace element deficiencies:

• Boron: Death of stem and root apical meristem, leaves twisted, young tissue most affected
• Cobalt: Used for nitrogen fixation, same as nitrogen deficiency signs (stunted growth)
• Copper: Young leaves dark green, twisted, wilted, tip remains alive
• Manganese: Chlorosis of young leaves, with smallest veins remaining green, necrosis between veins
• Molybdenum: Chlorosis, twisting, death of young leaves
• Zinc: Reduced leaf size, shortened internodes, chlorosis, spotted leaves, older leaves most affected
• Nickel: lack of germination or seed formation, required for iron absorption
