Seachem MultiTest Iodine & Iodide

My iodine levels were a total mystery until this kit—the 0.06 mg/L NSW reference point makes it so easy to know exactly where to aim. The color charts are clear enough that I trust the reading even in dim lighting, and it takes me under two minutes per test.

Been keeping a reef tank for years and always guessed at iodine levels, but this kit finally gives me a clear number to target that 0.06 mg/L natural seawater mark. The drop-by-drop titration is a bit fiddly the first time, but once you get the hang of it, the result is super consistent. Definitely

The color chart makes it easy to match the exact iodine level, and I love that it tests both forms in one kit. My reef tank’s corals seem much happier now that I can keep the dosage precise.
