Suggestions for this tank

Well, not that many sell the tenso cocktail, mostly in western Europe where their website not even support English, having to translate every page within their website, and absolutely none ship to Israel.

All the salts so far I have acquired from a supplier from India, shipping globally, probably well known, however this collection of micronutrients is more comfortable to aquire all in one, so this is an adequate product.

Tenso cocktail is found on online calculators, and under the diy category, that is, they are not considering it as a pre mixed, but raw dry salts mixture of trace elements for micronutrient solution

I need this product as soon as possible

Well, I'm about to order the csm+b, does it good?
But I ask myself, if I'm already mixing magnesium from dry magnesium sulfate, and iron is not a diy but easy life, though when finished I have no intention of mixing chelated iron independently, because a. Haven't found any dtpa online, b, not straightforward process as I understand, then do I really need those elements to dose ? Do I really need this product?

Well, it looks like csm b is even preferred for my purposes

Hi, tell me, I came to the understanding that the commercial iron fertilizer I use is practically useless with the pH which I haven't yet measured but absolutely 8 and beyond. So I just acquired EDDHA 6% which is active up to ph 9. About to mix some according to online calculator, but understand it might tint the water column. Should I prepare the diy iron fertilizer solution?
About to mix like 26 g to reach a target of 0.1 ppm and dosing two days of the week.

csm+b - yes, a common mix

EDDHA .... 0.1 ppm target ....common number, but I find iron overestimated; chemically it is a bit of a troublesome element, but that's about it. Even is precipitated and complexed in substrate, I assume microbes are able to make it bioavailable again for plant roots and plant roots manipulate the substrate to allow microbes to do so.

So if you worry about your water turning pink, dose conservative. I dose trace elements once a week for my new high energy tank, and mostly because I work with pure RO water.

So you suggest that
"At a very high pH, non-EDDHA iron chelates (like Fe-EDTA or Fe-DTPA) lose their stability, causing the iron to separate, oxidize into insoluble iron hydroxides, and precipitate out of the water column where it becomes unavailable to plants."
Could be consumed by roots later though the upper layers of the substrate?

BTW, 0.1 of that chelated isn't common it turns out, Dosing more than 0.02 ppm will start to tint the water

We always apply a single number for the pH in a tank, but in reality, pH varies very locally, also in nano tanks, and plants actively manipulate it in their near surrounding. And I'm not suggesting in the range of .1 or .2 but much more extreme.
