JBL Kugeln Root Balls
JBL 7 Balls are pressed fertiliser pellets, enriched by a special process with all the nutrients vital for aquatic plants, especially iron and trace elements. The nutrients are released slowly, providing a very favourable depot effect. The ball shape permits the convenient use in existing freshwater-aquariums. Especially suitable for the specific nutrient supply or post-fertilisation of aquatic plants which mainly absorb their nutrients through the roots, such as echinodori, cryptocory-nae, and others. Mix with aquarium gravel when setting up a new aquarium. Contains clay, which acts as nutrient store, binding excess nutrients and releasing them as required. Effective for at least 3 years and does not contain phosphates nor nitrates.
