Someone told me that we have to dose Flourish iron and micros after lights out. Is is true and if yes then why?

It is true that we should dose fertilizers after light off. Plants use nutrition 24 hours although at the time of photosynthesis they need more nutrition. At night, the chemicals spreads easily in the water and ready for next day photosynthesis.

in day time also it spreads well right, no?

Saikumar and Akshat Ji

Sometime water also get cloudy in day time fertilization due to reaction with light. Although I am not aware with the reaction but somewhere I read that Iron reacts in water in presence of light.

One more thing, Macro and Micro should not be dose at same time.

I'm not sure, but I guess it has something to do with stability of chelated( chelated iron) compounds in light.

yes.
Actually EDTA is sensitive to light. DPTA is not that much sensitive to light. Some companies use more stable chelates. Some use chelates that are easier to absorb in acidic Waters. Best thing is to know what's the composition in bottle and then dose or look out for what's written on instructions.

I have been reading about this exact topic.
From what I have read and understand, I think the best way is to dose little by little throughout the day.
Set your auto doser to dose ferts throughout the day. When you just dump all the chemicals in the tank at once, you give your tank a sudden 'shock'. If you keep the parameters constant by dosing the chemicals at a constant pace, your system doesn't get shocked and a non fluctuating system is always better than a fluctuating one.

This is what I understood from a few articles that Tom Barr has written. I don't have any first hand experience though. I myself am in the planning stage of my next planted tank. Does anyone have any counter arguments?

That's something ideal. But does it really matter if we shock the tank, and By this is it shocking plants or fish?

Also it quite a lot depends on your micros, if it is light sensitive. Lastly you d want to dose micros and macros at separate intervals to avoid oxidising Fe2+ or precipitating.

And as you are at it check out PPS way of dosing as well, nearly same schedule as you mentioned, but quite different in theory.

So far the best way of dosing but beginners like me doesn't have any auto-feeder
I will prefer to dose all at once and leave for my work, still didn't get any solid reason for dosing micros at night
Ludwigia Palustri starts getting greener from the day i started dosing ferts at night

Well its simple
1. If you dose in day time, you d have dosed even macros, which have capacity to react with Fe2+(from your Flourish iron)
2. Generally micros have tendancy to precipitate in presence of macros like above.
3. Some micros have iron included in them, and this iron is light sensitive, Seachem should be different to this.
4. Not sure if your friend meant it this way, but you can doze it AnytimeMorningNoonEvening but not overlap with macros.
5. Your plant turning green has an effect from not only iron but also your light and macros, so tell the whole story.

Does it make sense now?
