Easy-Life Ferro contains easily absorbable iron for water plants. Iron is essential for the good development of plant leaves. Iron ensures that the leaves are green thanks to the creation of chlorophyll. A lack of iron results in the leaves turning yellow, which is known as chlorosis. Ferro helps to prevent this problem. If there are fast-growing plants in an aquarium, then there is a good chance of iron deficiency. In that case, it is recommended to add Ferro to prevent problems.
