Description
API Root Tablets Card of 10 – Promotes the lush, beautiful growth of aquatic plants
API Root Tablets (Card of 10) are specifically formulated target-fertiliser tablets designed to deliver essential nutrients directly to the root zone of aquatic plants. Heavy root-feeding plants—such as Amazon Swords, Cryptocorynes, Vallisneria, and Lotus—absorb the majority of their nutrition through substrate rather than the water column. Packed with essential elements like iron, potassium, and carbon, these solid fertiliser tablets promote robust root development, prevent leaf yellowing, and stimulate lush, healthy foliage.
Benefits:
- Promotes lush growth of aquarium plants
- Contains Iron.
- Develops strong roots
- Pack of 10 Tablets
Usage & Application
When to Use
-
New Plant Setup: Place beneath newly planted root-feeders to accelerate root establishment and reduce transplant shock.
-
Monthly Substrate Replenishment: Add regular doses every 30 days to replenish depleted substrate nutrients in planted aquariums.
-
Nutrient Deficiency Treatment: Use when plants exhibit pale leaves, yellowing tissue, or stunted growth due to lack of iron or potassium.
How to Use
-
Use 1 tablet for every 194 sq. cm (approx. 30 sq. inches) of substrate surface area. As a rough guide, approx one per 13cm. A standard 38 L (10 US gallon) aquarium requires approximately 6 tablets.
-
Insert each tablet midway into the gravel or substrate bed near the base of root-feeding plants.
-
Replace tablets monthly for optimal plant growth. Add new tablets monthly for optimum growth.
-
Safe for all tropical fish, invertebrates, and shrimp. Works effectively alongside liquid fertilisers such as API Leaf Zone or API CO2 Booster.
