25 Root Sticks – Slow-Release Root Fertilizer for Aquarium Plants
The 25 Root Sticks are professional root fertilizers developed to deliver nutrients directly to the roots of aquatic plants. Each 55 mm stick is made from iron-rich clay that slowly releases essential nutrients over several weeks, supporting strong and healthy growth.
Thanks to a special pre-treatment, the sticks remain intact upon contact with water, ensuring a clean release without clouding the aquarium or promoting algae growth. Ideal for freshwater planted tanks, these sticks are especially effective for Cryptocoryne, Echinodorus, and Lotus, which absorb nutrients mainly through the roots.
They’re easy to use and breakable, making them suitable for tanks with shallow substrate or small-rooted plants. Perfect for aquascaping and densely planted tanks, where stable root nutrition is key to long-term plant health and water quality.
