What Does Algaecide Mean?

In gardening, algaecide is commonly used to prevent the growth of algae while killing any such parasite that can hinder plant growth and affect crop production.

Botanists normally differ between synthetic and natural algaecides. These substances are often used in hydroponics to prevent algae from hindering proper plant development and growth. In most cases, gardeners only need a small quantity of algaecide to protect their crops.

In hydroponics, algae can trigger pH swings and oxygen depletion, which can cause lasting damage to plants. Because algaecide is a biocide, it has been known to successfully eliminate algae and other water-borne pests without harming aquatic animals and plants.

In some cases, algaecide can even be used to eradicate moss from crops growing in humid regions. It is recommended to check the plant’s pH levels prior to applying an algaecide-based treatment.

Chemical algaecides are not recommended for hydroponic systems that contain fish (aquaponics) since the harsh components have been known to harm aquatic animals. Additionally, chemical algaecides can be harmful to delicate marine plants.

In many cases, gardeners often opt for natural algaecides, which comprise of enzyme-based solutions. It should also be noted that a small amount of algae growth in a hydroponics system is considered normal. Algaecides are used sparingly, in extreme cases. Following their application, preventing future growth is key and can be done in various ways, including preventing light from entering the nutrient reservoir.
