JBL Ferropol 24
Many vital trace elements cannot be added as long-term fertilisers, as they are very unstable and quickly combine to form other compounds in the aquarium and would break down. This means that they are no longer accessible to plants. However, since plants can only develop their full glory if none of the vital nutrients are lacking, JBL has developed a special fertiliser containing the delicate trace elements and other vital substances in an adapted form.
