API Leaf Zone – Aquarium Plant Fertilizer

API Leaf Zone  – Aquarium Plant Fertilizer

Essential nutrients for vibrant aquarium plants

 API® LEAF ZONE™ is a liquid aquarium plant fertiliser that supplies iron and potassium—two key nutrients needed for strong, colourful leaves and healthy growth. Its formula is designed to be absorbed directly through the leaves of plants.

If you notice your aquarium plants turning yellow, soft, spotty or just not lasting – it is a sign that they aren’t getting all of the nutrients they need to survive! Just like you would fertilise your lawn, aquarium plants often need fertiliser to stay healthy and green. Most planted aquariums you see (including the ones we have in the shop) are dosed regularly with fertiliser to get that lush, healthy look. 

Key Features

• Rich in Iron & Potassium: Promotes vibrant leaf colouration and prevents yellowing.
