Introduction

Feeding water column aquarium plants is an essential part of maintaining a healthy and thriving planted aquarium. These plants extract nutrients from the water rather than relying solely on substrate fertilizers. In this article, we will discuss the importance of feeding water column aquarium plants and what types of nutrients they need to grow and flourish.

Why Feed Water Column Aquarium Plants

Water column plants extract nutrients directly from the water, which means they do not rely solely on nutrient-rich substrate. Feeding these plants is essential for their growth and to prevent deficiency symptoms such as yellowing, stunted growth, and slow development.

Many aquarium owners make the mistake of thinking that they do not need to feed their aquatic plants since they are already adding fertilizers to the substrate. However, this is not enough to meet the nutrient requirements of water column plants. Feeding these plants ensures that they receive all essential nutrients necessary for healthy growth.

Nutrients Required by Water Column Aquarium Plants

When it comes to feeding water column plants, various nutrients are essential for their growth and development. These include:

Nitrogen: Nitrogen is critical for plant growth, and it is required in large quantities. Plants absorb nitrogen in the form of nitrates or ammonium. It is essential to monitor nitrate levels to prevent excessive growth of algae.

Phosphorus: Phosphorus is necessary for plant growth and is required in moderate amounts. Plants absorb phosphorus in the form of phosphate. A deficiency in phosphorus can lead to slow growth and weak roots.

Iron: Iron is a micro-nutrient required by plants in trace amounts. It is essential for chlorophyll production and overall growth. Iron deficiency symptoms include yellow leaves and stunted growth.

Potassium: Potassium is also a micro-nutrient required by plants in moderate amounts. It is necessary for the absorption of other nutrients and overall plant growth.

Types of Fertilizers for Water Column Aquarium Plants

Various types of fertilizers are available for feeding water column aquarium plants. They include:

Macro-nutrient Fertilizers: These fertilizers contain nitrogen, phosphorus, and potassium in the right proportions. They are commonly sold as liquid or dry fertilizers and provide a comprehensive range of nutrients required by water column plants.

Micro-nutrient Fertilizers: These fertilizers contain trace minerals required by plants, such as iron, boron, manganese, and zinc. They are essential for the healthy growth of water column plants and are usually sold as liquid fertilizers.

CO2 Injection: Carbon dioxide is a crucial component for plant growth, and adding it to the aquarium through CO2 injection can significantly improve plant growth. It can be achieved through pressurized CO2 systems or DIY yeast fermentation CO2 systems.

Organic Fertilizers: Organic fertilizers are made from natural ingredients such as fish waste, animal waste, and compost. They are a good option for those who want to avoid chemicals and prefer an eco-friendly way of feeding their water column plants. However, it is essential to monitor their use as they can raise nitrate levels in the water.

Conclusion

Feeding water column aquarium plants is essential for their growth and development. The type of fertilizer you choose depends on the needs of your plants and your personal preferences. Always monitor nutrient levels and adjust your feeding regimen accordingly to ensure that your water column plants thrive and maintain healthy growth.
