You mention that you test for iodide and use the Hanna checker, but it tests for Iodine, not iodide, and the resolution is in increments of .1 ppm. My understanding is that the reef tank should be at about .01 ppm.
What Iodine levels are trying to maintain? Or iodide levels and how do you determine Iodide from the Hanna checker?
