JBL Manado Dark is a natural product. Initially, there may be a slight increase in iron content and hardness values. This will normalize after several water changes. Harmless iron blooms may occur in soft water. Rinse JBL Manado Dark briefly in tap water before use to remove any abrasion caused by transport. If iron flowers appear, there is no need to worry. They pose no danger to your invertebrates and fish. Plants absorb the iron through their roots. You can suck up the iron flowers with a fine air hose, stir them into the substrate, and change 50% of the water every other day for the first 10 days. This will reduce the effect.
No, because the iron is already oxidized and no longer freely available in the water. Plants can reabsorb it through their roots if you do not remove the flowers completely or stir them into the soil.
