JBL The 7 +13 Balls (20 balls) are pressed fertilizing 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. Specially suitable for the specific nutrient supply or post-fertilization of aquatic plants which mainly absorb their nutrients through the roots, such as echinodori, cryptocory-nae, and others.

Depending on size of the aquatic plant, press one or more balls into the ground around the roots. Repeat after one year
