    I had a problem with STN some weeks ago. After reading this article: Iodine I tested and dosed Iodide as my level was 0.

    Here is the coral approximately 3-4 weeks ago.

    Here is the coral today with an Iodide level of 0,06ppm in my tank.

    Looking much better dude. I have also begun dosing Iodine, but very small dosages as I still need to obtain a test kit for it.

    Jacques, not only the growth. Look at the colour of the tips.

    That is the problem Mek.... you need to dose iodide, as this is the biologically available type of iodine. Total Iodine level including iodate can build up in your tank and your iodide kit will not pick this up, thereby reaching dangerous levels.

    That is 100% correct bud.
    Which one you using, Lugols?

    Help me out here please, I'm hell confused :p

    You're talking about Iodide, Iodine and Iodate, are these all different things?

    good stuff that, they use loguls solution, so its water based, where as iodine tincture is alcohol based

    good stuff mudshark!

    Interesting.

    Your algae filter no doubt is removing a lot of iodine from the system. Probably a lot faster than in a normal system too, making Iodine deficiencies more likely.

    And there are more members of the iodine family. The only one that is biologically available to fish and invertabrates is iodide. This is the one that most test kits measure and that we need to have a level of 0.04-0.08ppm of in our tanks. Iodate is useless to invertabrates but can build up to dangerous levels in our tanks if we dose iodine. Iodate can however be converted to iodide in the dsb but not the reverse. So if you dose iodide you don't run the risk of increasing iodate which is not being used up by livestock. That's how I understand it. The article on iodine is much clearer than my brief explanation.

    Nice Broder - I dose the pure reef iodine, my colour is fantastic.

    I have the same coral, is this just the basic staghorn?

    Me too been dosing iodine. Previously my corals can hardly survive but after dosing, the growth is going wild. Even the button on the side of the rock open up. For my tree, current one in the tank is a very small branch, the main one die off previously. Now this small branch already growth from 1cm to 12cm and survive since i dose the iodine.
    Iodine (Kent) dosing for me approx 15mm every 2 week.

    I use the Seachem iodide test kit. I see that quite a few of you are dosing iodine. I just want to reiterate that you must then test for iodine and not iodide. If you test for iodide, it will not measure the amount of iodate in the water. Iodate is not used in the system, and will build up to dangerous levels, even if a little is converted to iodide in the anaerobic regions of your tank.

    As for every additive, test before adding. You wouldn't add more salt to your tank without knowing what the salinity is, would you?

    Yip... it was the first sps frag that I tried about 2,5 years back. I would have been devastated if it would have died.

    Would you say using this instead of the commercial brands is going to do the same trick?

    It will do the same thing. I also tried to get potassium iodide from the chemist, but they didn't stock it and it would have cost as much as the branded products from the LFS.

    I'm no longer convinced that iodide or the lack thereof was the cause for any of my previous staghorn stn problems. The coral, and some others, have recently gone into decline again, despite the iodide levels being where they should be. I suspect that it could be because of fluctuating alkalinity level. It went from 7.8 to 9.2 and back to 8.3 in the space of 2 weeks!
