Iodine is a trace element present in reefs all around the world, being one of the most important elements for all animals and plants in our aquariums. Iodine has been known to have a positive impact in aquariums where macro algae is present and to impact the blue colour of the genus Acropora.

Iodine gets depleted from the water in our tanks very quickly. Therefore, it is important to check its levels through an ICP analysis and ensure adequate levels and stability by dosing Iodine as needed.

Iodine in seawater varies widely but, it is vastly agreed that a 60 µg/l level is ideal.

Iodine Zlement used in conjunction with a regular testing procedure, allows any reefer to make corrections to Iodine levels ensuring the levels in their tank water stay within the best range for their friends.

​1 ml of Iodine Zlement increases the Iodine concentration of 100 litres by 100 μg/l.

IMPORTANT NOTE: Iodine dosing is quite safe, however in high doses is toxic for all animals and will kill them. Do not overdose and ensure adequate levels by regularly testing.
