AF Lab Iodum is a highly concentrated iodine supplement for reef aquariums. Iodine plays an important role in general cell function and the transfer of nutrients between cells. Because iodine is continuously consumed by aquarium inhabitants, its concentration can decline quickly without regular supplementation.

Corals use iodine when synthesizing pigments that help them adapt to changing lighting conditions and protect delicate tissues from UV radiation. Maintaining appropriate iodine levels can also help intensify dark blue and purple coloration in hard corals and support normal molting in shrimp.

10 mL of AF Lab Iodum increases the iodine concentration by 0.1 mg/L (ppm) in 100 L (27 US gal) of aquarium water.

Every aquarium is different, and the appropriate dosage will depend on coral stocking and the individual needs of the system. Both deficient and excessive micronutrient levels can negatively affect aquarium inhabitants. Adjust dosing based on regular water testing.
