Floating plants are the solution to various aquarium algae! Besides simply floating, they have many positive effects on aquarium water. In this article, I'll explain all the uses of floating plants.

Floating plants will save your aquarium from algae!

Floating plants are an excellent solution for controlling unwanted algae in your aquarium. Not only do they add beautiful aesthetics to your underwater world, but they also play a crucial role in maintaining water quality and limiting algae growth. In this article, I'll explain why floating plants are essential for a healthy aquarium.

Floating plants inhibit light and reduce algae growth

Floating plants like Limnobium and Phyllanthus fluitans float on the water's surface and form a natural barrier against bright light. By filtering the light that enters the aquarium, algae have less opportunity to grow. Less light means less energy for algae to develop, resulting in a cleaner, algae-free aquarium.

Floating plants absorb excess nutrients

Floating plants are also excellent nutrient absorbers. They absorb excess nutrients like nitrates, which would otherwise be used by algae for growth. This helps further limit algae growth and contributes to stable water quality.

Floating plants as indicators of plant nutrition

Floating plants can serve as natural indicators of nutrient levels in your aquarium. For example, if Limnobium turns darker green, it means there's a high nitrate level. If the leaves become lighter in color, there's likely a nitrate or plant food deficiency. Phyllanthus fluitans is an exception; this plant turns red when it has low nitrate levels and green when nitrate levels are high.

In short, floating plants are not only a beautiful addition to your aquarium, but they are also powerful allies in the fight against algae. They help keep your aquarium healthy by limiting light, absorbing nutrients, and acting as natural indicators of water quality.
