Tropical Aquaflorin Potassium is a liquid potassium fertiliser for planted aquariums, useful when plants need potassium without extra nitrogen or phosphorus.
Tropical Aquaflorin Potassium is a liquid potassium fertiliser for planted freshwater aquariums. Use it when aquatic plants need targeted potassium support without adding nitrogen or phosphorus.
Potassium helps aquarium plants maintain strong leaves and steady growth. Low potassium is often associated with pinholes, weak older leaves, yellowing leaf edges or growth that stalls even when light and other nutrients are available.
| Product type | Liquid aquarium plant fertiliser |
|---|---|
| Available sizes | 30 ml and 500 ml |
| Best use | Potassium support for planted freshwater aquariums |
| Dose guide | Retail guidance commonly lists 10 ml per 100 litres; follow your bottle label |
| Not for | Fish feeding, disease treatment or replacing normal water care |
Dose from the label and start conservatively, especially in nano tanks, shrimp tanks or lightly planted aquariums. Watch plant response over several weeks rather than chasing instant results with extra fertiliser.
Plant fertiliser works best with stable lighting, sensible feeding, regular water changes and suitable carbon or CO2 support. Avoid mixing multiple treatments unless the product labels say they are compatible.
For iron support, compare Tropical Ferro-Aktiv. For liquid carbon support, see Tropical Carbo. For broader planted tank fertilisers, compare Tropica Premium Nutrition and Tropica Specialised Nutrition.
