Premium Potassium Supplement for Planted Aquariums
Flourish Potassium™ 500ml contains 50,000 mg/L of potassium, specifically formulated for the natural planted aquarium. Potassium is an essential macronutrient required for strong plant growth, healthy leaves, and robust root development.
In fast-growing aquascapes or aquariums with low-mineral source water, potassium can quickly become depleted — leading to poor plant health. This supplement helps prevent deficiency and keeps your plants thriving.
✅ Why Choose Flourish Potassium?
✔ Highly concentrated – 50,000 mg/L potassium
✔ Targets potassium without affecting nitrogen (N) or phosphorus (P)
✔ Derived from potassium sulfate (does not alter NPK balance)
✔ Ideal for aquascaping & high-tech planted tanks
✔ Suitable for freshwater planted aquariums
Unlike potassium nitrate or potassium phosphate, this formula allows you to adjust potassium levels without changing nitrogen or phosphorus levels, making precise nutrient control easy.
🌱 Prevents Common Potassium Deficiency Signs:
Yellowing (chlorosis) in older leaves
Brown/dead patches (necrosis)
Pinholes in leaves
Weak stems and roots
Slow or stunted growth
📏 Dosing Instructions:
Use 1 capful (5 mL) per 125L (30 US gallons)
Raises potassium by 2 mg/L per dose
Dose 2–3 times per week or as needed

Premium Iron Supplement for Planted Aquariums | Fast Foliar Absorption | Prevents Chlorosis
💚 Restore Vibrant Green Growth
Iron is immobile in plants, meaning it cannot be transferred from older leaves to new growth. When iron is deficient, symptoms appear first in young leaves, causing:
✔ Yellowing (chlorosis)
✔ Pale emerging leaves
✔ Short, slender stems
✔ Progressive lightening of new growth
Flourish Iron™ provides iron in the preferred ferrous (+2) form, allowing rapid uptake and correction of deficiencies in planted aquariums.
🔬 Why Iron Form Matters
When selecting an iron supplement, the oxidation state is critical:
❌ Ferric Iron (Fe³⁺)
Only soluble below pH 5.5
Precipitates in typical aquarium pH
Settles into substrate
Not available for foliar absorption
Often chelated as Iron-EDTA
Requires plant energy to reduce to ferrous form
✅ Ferrous Iron (Fe²⁺)
Soluble at all aquarium pH levels
Immediately bioavailable
Easily absorbed through leaves
No energy wasted on reduction
Flourish Iron™ uses a ferrous iron gluconate complex (not a chelate) for superior availability.
🌱 Advanced Formula Advantage
Highly Concentrated – 10,000 mg/L Ferrous Iron
Unlike iron-EDTA products:
✔ Weaker bonding than EDTA = better release
✔ Faster plant uptake
✔ No physiological energy drain
✔ More effective foliar feeding
✔ Provides additional carbon via gluconate
Despite common myths, ferrous gluconate is safe for fish and plants when used as directed.
🐠 Ideal For
High-light planted aquariums
CO₂ injected systems
Red plant enhancement
Rapid growth aquascapes
Correction of iron chlorosis
Professional aquascaping layouts
Perfect for gallery-style planted systems such as Nature Aquariums, Iwagumi layouts, Dutch style tanks, and contemporary aquascapes.
📌 Key Features
• 10,000 mg/L ferrous iron gluconate
• Immediate bioavailability
• Prevents yellowing in new growth
• Supports chlorophyll production
• Safe for freshwater planted tanks
• Professional-grade concentration
🌿 Symptoms of Iron Deficiency
If you notice:
Yellow new leaves with green veins
Increasing paleness in each new leaf
Weak stem structure
Your plants are likely iron deficient — supplement promptly for optimal results.
