Well, that was the only anomaly in my ICP tests for the previous several months. I didnt think much of it since on this particular ICP test (oceamo), because it isn’t highlighted elevated until you get above 2 ug/l. I didn’t notice the climbing trend. I saw a general decline in all tenuis, and overall less polyps extension through the reefs, as well as lighter colors, and random rtn here and there (I generally don’t lose much). This is in 4 separate reefs plumbed into 2 separate systems (both getting dosed daily KZ flatworm stop).
I slammed the systems with milbemycin multiple times thinking it could be white bugs but saw no of difference. After consulting with moonshine owner, he confirmed that this product does indeed contain copper, and varied amounts from bottle to bottle. I’ve also spoke to many KZ flatworms stop users, who tend to be old-school stick heads like myself. Many of them are having the same coral paling issue and random losses. They confirmed high copper levels as well using MS-ICP.
Now, could my observations be wrong, of course. But my copper is back down well below .1 and my tenuis are looking great again, not to mention my Goni no longer close up which was another observation. Whether it was the copper or source of iodine or the relation between the 2, it was from the use of that product.
