I have been in contact with Red Sea. They were out of stock but eventualy provided an iron test kit refill for free which works properly. I also have discovered that running activated carbon removes iodine which explains why I never have an iodine present in my system. I am giving this a 5 start review to counteract the 2 star previously given. All in all, I feel it's a 4 to 5 star product. Weather dosing these is usefull or not is hotly debated. But if you do, Use this kit.

Bought this kit. I am a skeptic by heart and I love the idea of being able to dose things based on there actual levels and not just "add once a month" etc. The Iodine and Pottassium tests seem to be working but the iron test reads 0 even when I add a drop from the Iron supplement bottle. It is not uncommon that a test solution will get stale after a few months and stop working. I have emailed Red Sea to see if they will send me a iron test refill kit. Over all I'm starting to think that knowing what colors are "Dull" and dosing based on that might be a better Idea. If it ain't broke, don't overdose it.

I am still debating the value of this test kit, and the experts are still debating the need to dose these. Usually water changes will provide what is needed, but this kit will let you know if you are within a range of parameters.

If you dose I2 and K you should get this. I try and get the most out of my SPS so I dose and check the range with this kit. I don't have much of a use for the Fe, but I'm sure to use it sometime. Still a great value and if you dose I2 and K don't guess and think your tank is OK, because it will crash and you will be sorry. This kit is effective and because of the refills it is cost effective.
