Iodine and Zoas

[Fishhead1]

I've heard mixed opinions on iodine dosing and Zoas. What's the consensus?

I have heard it helps produce zoa growth and coloration. The only downside is if you dose too much you can crash your tank

With iodine, if you're not testing for it be extremely careful in my opinion. I dose daily, 7 drops in 100g and test monthly with icp to ensure it stays in the safe range. I do see benefits with my zoas for sure... I use the seachem reef iodide in a dropper. I started with an icp test & then 3 drops a day, tested again moved to 5, then 7, then 10 and after that test it got a little too close to the recommended cap for my comfort so I dropped back to 7 and thus far it remains very stable.

I dose once a well, its very concentrated so a little goes a long way. Its especially useful for weeks between water changes. Its also very therapeutic to use in dips for stressed or recently fragged corals.
