There seems to be growing confusion in the reefing world over the Hanna iodine checker.
This checker is not designed to either measure the forms present in seawater (iodide and iodate), nor for the low concentrations present (0.06 ppm in NSW).
It has no use in a reef tank
It might be useful for a spa or pool if you sanitize it with iodine.
Happy reefing!
