So I measured wrong when dosing DIY Molybdenum, used g instead of mg on the scale, and essentially 1000x the dosage..... the Molybdenum level according to my latest ICP is at 4 mg/L, down from 4.7 mg/L a month ago. The target level according to the ICP should be 0.010 - 0.015 ug/L. It's been 4 months since I dosed the Molybdenum, and there hasn't been any noticeable effects on the livestock. This system is fairly large, so I would rather use some kind of media to remove the Molybdenum. In the past month, I've used cuprisorbs in a media bag and it seems to have removed about 10% of the Molybdenum. The only other export would be through the skimmer. Now I'm trying cuprisorb in a media reactor in hopes of removing it faster. I know it'll also remove other trace minerals, but I have trace minerals on a doser, so it shouldn't deplete completely.

I'm looking for suggestions, if there are other medias/methods to remove Molybdenum that is more efficient than Cuprisorb.

Molybdenum can only be reduced slowly in a reef tank. Regular water changes, activated carbon and filtration via aluminium-based adsorbers are helpful. Water changes is the best way for reduce the crazy high Mo level

Higher Molybdenum values have hardly any influence and are well tolerated, too low values should be avoided as the light protection mechanisms of corals are also dependent on molybdenum. Vanadium and molybdenum also play an important role in the colouring of the corals and should be detectable in the correct ratio of approx. 1:3–1:4. (target value vanadium 3–5 µg/l (0,26 US.liq.gal.), target value molybdenum 12–15 µg/l (0,26 US.liq.gal.)).

High molybdenum levels can promote the growth of cyanobacteria in the absence of inhibitors and if the organic load is too high. However, a high molybdenum value alone is not alone responsible for this.

Say what,

How exactly does that work?

Also what colour?

Just curious…

Seems like I need to get a bottle of molybdenum and vanadium lol…

Where does this info come from? Hopefully not an AI. :)

Some of the comments seem odd to me.

Like vanadium, molybdenum is a transition metal, essential and part of the Dynamic Elements as it is needed in many enzymatic processes within the nutrient cycle and within the cell functions. A lack of molybdenum should be avoided, because a nitrate reduction is not possible without molybdenum. Here molybdenum acts as a component of the important enzymes in the nitrogen cycle.

I have no idea of what colors does molybdenum affect. But if lack of molybdenum can result in higher nitrate level, then it can affect most coral colors by high nitrate level.

It is a needed metal. If levels are so low that it is causing issues, corals will suffer. Anything beyond that about colors, cyano, etc. is unsupported speculation.

I think the AI's hallucinations are more informed and accurate than the source of much of this... that is, until the AI starts listening to the source.

Everybody responding with AI these days. Heh.

AI is annoying and too many people accept that information as fact.
