Tropical Ferro-Aktiv Iron Fertiliser for Aquatic Plants 500ml

Tropical Ferro-Aktiv 500ml is a dedicated iron supplement for planted aquariums. Iron is a core component of chlorophyll — the pigment responsible for healthy green colouration in aquatic plants — and deficiency quickly shows as pale, yellowing leaves and stunted growth. This product is designed for systematic, ongoing iron supplementation to keep planted tanks thriving.

Why Iron Matters in a Planted Tank

Chlorosis — the yellowing of leaves caused by insufficient iron — is one of the most common signs of nutrient deficiency in aquatic plants. Without adequate iron, plants cannot produce chlorophyll effectively, leading to visible deterioration and inhibited growth. Tropical Ferro-Aktiv 500ml addresses this directly by providing a reliable, consistent source of iron for your aquarium flora.

How to Use

• Dose at 10ml per 100 litres of aquarium water
• Apply at least once weekly, ideally during water changes
• For densely planted setups, smaller and more frequent doses are recommended over a single weekly application

Suitable For

Any freshwater planted aquarium where iron supplementation is needed. Particularly relevant for high-plant-density tanks where iron is consumed more rapidly and deficiency is more likely to develop between water changes.

Used consistently, Tropical Ferro-Aktiv 500ml supports vibrant green growth and helps maintain the visual quality of a planted aquascape over the long term.
