Plant food & fertilizers for your aquarium

A healthy aquarium starts with strong aquatic plants. Plant food and fertilizers form the basis for a well-balanced ecosystem in your aquarium. By adding essential nutrients – such as iron, potassium, and CO₂ – you give your aquarium plants the power to grow, produce oxygen, and convert waste products. This is not only good for your plants, but also for your fish, shrimp, and other aquarium inhabitants.

What types of plant food are there?

This category includes liquid fertilizers, substrate capsules, nutrient substrates, and complete plant nutrition systems. Whether you use a CO₂ system or have a low-tech aquarium, there's a suitable solution for every type of setup. Liquid plant nutrition is ideal for fast-growing plants, while tablets or capsules provide long-term nutrition at the roots.

When do you use plant food?

Plant nutrition is essential when setting up a new aquarium, but also during the weekly maintenance routine. Yellow leaves, holes in leaves, or stagnant growth are often signs of a nutrient deficiency. Targeted fertilization prevents algae growth, keeps plants strong, and ensures a stable biological balance.
