High Iodine when using Tropic Marin Balling Part C

[RelaxingWithTheReef]

Ten months ago I switched from B-Ionic 2-part to an equivalent potency 3-part solution. 607g/gal BRS Soda Ash, 841 g/gal BRS Calcium Chloride, and 276 g/gal Balling Part C. The method has been working great as confirmed by ICP-MS.

The iodine usually comes in around 40-60 ug/L. Then out of nowhere (after using a new box of Part C) ICP comes back at 505 ug/L in one tank, and 668 ug/L in another! Shortly thereafter, one of my high alkalinity consumption tanks tested an astounding 960 ug/L!

I was able to confirm the ICP iodine levels using dilution, verification with Iodine standards, and the test here:

Long story short, I believe the source is the Balling Part C.

Verification - 250 ml of fresh Blue Bucket seawater measured 64 ug/l. Adding 3 drops (0.144 mL) of my Part C mix (approximately corresponding to my daily dose of 4.5 dKH alkalinity), increases the iodine level to 120 ug/L. This seems like an incredibly high amount of iodine increase.

@Randy Holmes-Farley @Hans-Werner any thoughts on what could be going on here?

I am curious if I’m simply the lucky one or if there are other users experiencing unexplained iodine rise while using Part C.

I've not heard of this issue before.

If the Balling Part C was at fault, it would have to be from mismanufactured or later adulterated batch. It cannot raise iodine that much when formulated as claimed, regardless of how much you add (unless salinity was allowed to rise very high).

Following as my last ICP came back with very high iodine. Is there a way to abate the iodine other than just thru water changes?

Not really. Growing a lot of some types of macroalgae will consume a lot of iodine.

Thank you.

I have not seen the issue when I switched to DIY Balling using TropicMarin Part C. Using some ISOL8 I in my daily dosing solution

I would contact the manufacturer. They should be interested in a sample. They may need to recall.

That's strange. I use TM Balling C and the ICP test shows normal levels, but I also add iodine.
