Why should I test iodine in a reef aquarium?

This iodine test kit enables the accurate dosing of iodine to your fish tank. It is important not to overdose iodine because it can cause harm to your corals. However, if the iodine levels are non existent, many corals will not thrive. This is the main reason that it is important to measure iodine.

You cannot get enough iodine for coral growth, colouration and health from water changes alone. This is why Red Sea have created the Trace Colours programme. Through in depth research, they have identified 31 minor and trace elements in addition to the foundation elements present in the skeleton and soft tissue of al corals. Iodine is one of these trace elements, and quite an important one.

Not just for coral keepers…

If your marine tank has a lot of macroalgae, coralline algae or crustaceans you may find that you have a higher demand for iodine than most would expect. There may be a few clues, like the algae bed not growing as quickly as you expect, or perhaps shrimp are struggling to shed their exoskeleton. But, the only way to know for sure, is to test the water.
