I believe the Seachem team has some monkeys running around the office making instructions. Put simply, they are unclear and difficult to understand. iodide2 sample? When this is the case, they call the same item by different names while giving directions, which is very confusing. You'll be scratching your head for 3 hours to make sure you're reading this correctly. Worse, there are many parts and many steps to get the result. I ended up doing iodine testing for a while after this purchase.
