Guaranteed analysis
Nutrient contents and chemical forms
The manufacturer currently publishes the N–P₂O₅–K₂O values below. A complete trace-element breakdown is not published on its product page; we do not infer it from another Thrive formula.
| Total nitrogen (N) | 2.57 % |
|---|---|
| Available phosphate (P₂O₅) | 1.69 % |
| Soluble potash (K₂O) | 10.1 % |
Percentages describe the fertilizer, not a target concentration in your aquarium. Phosphorus and potassium are declared as P₂O₅ and K₂O.
Nutrient sources
The manufacturer describes a blend of macro and micronutrients for the root zone. The detailed ingredient list must be checked on the supplied label.
A routine that supports the formula
Observe new growth, keep lighting consistent and maintain filtration. Consider the nutrients supplied by feeding, substrate and other fertilizers before changing your dose. Follow the label on the bottle you receive.
