TROPICA Nutrition Capsules are a real boost for nutrient-hungry aquatic plants. Designed to be placed directly in the substrate, they slowly release essential nutrients right where the plants need them most: at the root level . Each capsule gradually releases nitrogen, phosphorus, iron, and micronutrients over several weeks, promoting healthy, consistent, and noticeable growth. Easy to use, they blend discreetly into the gravel and work continuously without clouding the water. Ideal for plants with extensive root systems, this convenient format allows for optimized nutrition without over-fertilizing or demanding maintenance.
These capsules have been designed to meet the specific needs of aquatic plants with extensive root growth. Once placed in the substrate, they gradually release a balanced mix of major nutrients and trace elements , ensuring a constant supply for one to two months . This slow release prevents nutrient spikes and supports stable growth, even for the most demanding plants.
Plants with thick stems and extensive roots benefit greatly from this type of localized fertilization. The capsules are easily placed near the roots using tweezers, without disturbing the aquarium's layout. The result: denser leaves, more vibrant colors, and a visibly more vigorous plant, without negatively impacting the water's balance.
Even after the nutrients have been fully released, the capsules do not disappear completely. The remaining small beads are composed of a completely harmless resin , safe for fish, invertebrates, and microfauna.
Easy-Life 25 Root Sticks are ideal for feeding plants directly at the root . The product contains 25 special clay sticks which are very nutritious and have a high iron content.
Tropica Nutrition Capsules are slow release fertilizer capsules for planted aquariums. They contain nitrogen, phosphorus, iron and micronutrients . Fertilizer capsules are beneficial for fast growing plants and for enhanced growth and color.
