Chronic Severe Iodine Deficiency

Basically I'm having to do 20%+ water changes a week else some acros and montis start to get grumpy then lose tissue. Would a lack of Iodine cause this? I feel like doing water changes to supplement >something< but not actually having any idea of what that something is...

Foxface, 2 Clowns, Royal Gramma, Diamond Goby, Midas Blenny, Longfin Fairy Wrasse
19 acros ranging from frags to small/medium colonies, 3 montis (1 cap, 2 encrusting), leptoseris, stylophora, pocillopora, cyphastrea, 2 euphyllia (hammer and frogspawn), RBTA, and various zoanthids.

Reef Octopus 152 skimmer
Geo 618 Calcium Reactor
2 MP40s

Ordering a Reefer 750xxl within the next couple weeks which is why there's a giant calcium reactor, and 2 MP40s on a small tank. That said part of me wonders if the excessive size of the skimmer for the system is contributing to or even causing the issue.

You have a lot of things that are too low to be detected, many of which are necessary elements (vanadium, zinc, manganese, chromium, cobalt, iron, etc.). I don't have any reason to think iodine is causing your issues (I stopped dosing it since I never saw a benefit), but it is easy to experiment with it and other trace elements and see if there's a benefit.

Maybe try a commercial mix since so many are low. Iodide would usually be a separate supplement.

I had a similar report (many trace metals undetectable). I added Aqua Forest MicroE to my daily routine. When I compared what it provided to my ICP result, everything MicroE provides, is what I was undetectable on. YMMV.

When you added it, did you see any change in the appearance of the aquarium?

Did you feed nori? I suspect that nori could supply micro doses daily that it doesnt become a severe limitation causing deficiency symptoms.

I do not. My foxface has no interest in it.

Both your P and po4 are very low imo.

I doubt iodine deficiency is your issue, even if Triton is giving you a reading of zero. But if you want to supplement, you can use a tiny amount (1 or 2 drops for that tank size) of Lugol's directly into the overflow once a week, and you'll be fine. It is very very easy to overdose iodine supplements, and almost all of them recommend using too much.

As long as there's some, it's not too low. When I was being way too aggressive with GFO, I got a Triton result back with a 0.000 phosphorus. It actually gave me a chill as I read the result. That is definitely too low, as some corals made abundantly clear.
