What are API Root Tabs designed to do?

API Root Tabs are formulated to promote strong root development and support lush plant growth in freshwater aquariums. The product is intended for two stages of a planted aquarium: helping new aquatic plants get a vigorous start and helping established plants continue flourishing. This makes the tabs relevant when adding plants as well as when maintaining an existing planted setup.

The plant-growth purpose is tied to root development, rather than being presented as an all-purpose aquarium treatment. The product is specifically for freshwater aquarium plants.

• Supports root development for freshwater plants.
• Made for both newly added and established aquatic plants.
• Focused on plant fertilizing in freshwater aquariums.
