I recently learned that the salt I use apparently has no iodine...so I will now dose weekly to get the levels where they need to be. I was told that Tech-I is pretty good...any experience with this brand?

Also, I read somewhere that macro algae needs iron. I use Essential Elements and Coral-Vite weekly (both of which have some iron) - but is this enough for the macro algae? I will run an iron test to see where I'm at before I do anything. I don't know if the salt I use has iron...it's Red Sea Coral Pro. The label says nothing about iron and the website wasn't very helpful. Neither was their customer service. :devil:

Thanks,

Macro Algaes do need iron, but I heard or read somewhere that too much iron can be harmful above a certain level, to your corals maybe? Just dose small amounts and make sure it doesn't get high and you should be ok.
 
It is difficult for iron to reach elevated levels in seawater, because it tends to precipitate as iron hydroxide. Other than calcium, alkalinity, and magnesium supplements, iron is the only other supplement that I can even recommend adding. I don't like to add iodine because it is difficult to properly test (not to mention its different forms in seawater) for and plenty tends to be added in food.
 
Thanks for the replies; I've bought Lugol's solution to help me increase the iodine levels.

I may change to Reef Crystals after I use up the Coral Pro salt. Any experience in switching brands? I've read somewhere that it might be somewhat risky...but I think if I do it gradually, it should be fine.

Thanks again,
