Tropical Aquaflorin Potassium

Tropical Aquaflorin Potassium is a multi-ingredient liquid potassium fertiliser designed specifically for aquatic plants. It delivers targeted macronutrient support without introducing nitrogen or phosphorus, making it a precise tool for planted aquarium maintenance rather than a broad-spectrum supplement.

What It's For

Potassium deficiency is one of the more common and overlooked causes of poor plant health in aquariums. Aquaflorin Potassium is particularly well suited to new aquarium setups in the early months of establishment, and to any system where nitrogen and phosphorus levels are already elevated — typically where fish stocking is dense and waste breakdown provides those nutrients naturally.

No Nitrogen, No Phosphorus

Because this fertiliser contains no nitrogen or phosphorus, it won't contribute to the nutrient imbalances that drive algae growth. In heavily stocked tanks, fish waste already supplies these elements in quantity — adding more through a general fertiliser risks tipping the balance. Aquaflorin Potassium addresses what's actually missing without compounding what's already in excess.

Algae Control Through Balanced Nutrition

Providing plants with the specific nutrients they lack — rather than overloading the system — helps reduce the conditions that favour algae. A well-nourished plant population is better placed to outcompete algae for available resources, contributing to a cleaner, more stable aquarium environment.

Dosage

Apply at 10 ml per 100 litres of aquarium water. Consistent, measured dosing allows plant health to be managed accurately without guesswork.

Available Sizes

Aquaflorin Potassium is available in a range of bottle sizes to suit aquariums of different scale — from smaller planted tanks through to larger or multiple-system setups. Select the appropriate size from the options on this page.

For any planted aquarium where potassium is the limiting factor, Aquaflorin Potassium gives keepers a clean, targeted way to support plant health without disrupting the wider water chemistry balance.
