    Hey guys/gals,

    Tested my Iodine today with a Salifert test kit (New).

    I'm a bit freaked out because I'm unable to detect Iodide nor Iodate.

    Both tests show up as crystal clear and that includes the 2 part test of iodate. Am I missing something or can it be possible? I changed over to a new tank 2 weeks ago so lots of fresh salt mix went into the system. I have however added quite a few sps pieces and I do have a huge caulerpa farm which I have read could obsorb iodine.

    I would have believed the test if I didn't add all the new salt mix about 2 weeks ago but can't believe that it could have been absorbed that fast.

    I can't really tell if corals have less colour because my water is a bit cloudy from a biopellet bacterial bloom. My shrimps have beem extra shy though and haven't seen any of them molt in awhile now.

    Advice? (Got a bottle of Brightwells Iodine on hand).

    Well, iodine doesn't stay long in the water as it gets used up and quickly removed by the skimmer. Iodine gets added to the tank through foods as well. If the test kits are accurate and not expired, maybe dose a little, wait for it to mix well and test again.
