Complete Nutrition in One Formula

Aquatic plants absorb nutrients through both their roots and leaves. A quality liquid fertilizer delivers nutrients directly into the water column, making them readily available to stem plants, epiphytes, floating plants and other aquatic species.

Thrive combines the nutrients plants use in larger quantities with essential trace elements in one balanced formula:

• Nitrogen: Supports active growth and lush green foliage
• Phosphorus: Contributes to energy transfer and root development
• Potassium: Supports overall plant health and resilience
• Magnesium: Plays an important role in chlorophyll production
• Iron: Supports chlorophyll formation and healthy natural coloration
• Trace elements: Includes manganese, boron, zinc, molybdenum and copper

Simple, Precise Dosing and Dosing Instructions

Dose 1 mL per 5 gallons of aquarium water, 1–3 times per week. Use the included graduated dosing cup to measure the appropriate amount, then add Thrive directly to the aquarium.

For lower-light, low-tech aquariums or tanks with slower-growing plants, begin with one dose per week and adjust gradually based on plant growth and nutrient demand. More heavily planted aquariums may benefit from more frequent dosing.

A standard dose of 2 mL per 10 gallons adds approximately:

• 7 ppm nitrate (NO₃)
• 1.3 ppm phosphate (PO₄)
• 5 ppm potassium (K)
• 0.25 ppm iron (Fe)

Consistency is key. Regular, appropriately adjusted dosing helps maintain a dependable supply of nutrients for continued plant growth.
