things picked up alot plants coming back very nice and big leaves,
Now i got my self a FE test kit.
i tested the water and 0ml registered..
i keep dosing and i keep testing ,again and again , 0 0 0,
i added a drop of Iron directly in to the test tube to see if the solution works and it does..
now i already added 40ml in the last 12h and still 0...
my question :
do is still go ahead and dose more and more till i get any reading??
The recommended level is under .5 ppm. If you calculate the dosage correctly via the calculator, I won't worry about not having enough iron. Yes, you can overdose iron... Makes sure you are calculating your iron dosage level correctly.
I just did the calculation. Well, 2ml to a 200L tank would only give you .1 ppm. Hardly detectable by most kits, I think. Try to add more per the EI dosing schedule...try 6 to 10ml.

calc says to maintain 0.1ppm dose 2ml daily..
i dont get any reading att all not even after 40ml
according to the calculater i should have 2.0ppm with 40ml, tested and still 0?
any change the plants needed iron really bad and everything i dose will be used straight away???
Q: I've got a 40 gal heavily planted tank with Flourite substrate. I started dosing with Flourish Iron a few weeks ago due to pale leaves on pennywort, etc. The color has improved. I'm adding a capful every day to the tank; an hour after adding, my tank shows no iron with the Hagen test kit. Are the plants grabbing the iron? Or is it precipitating out somehow.
A: I am confident that the iron is being consumed. If it was precipitating out of solution, you would notice a white chalky haze to your water and a white colored coating to your aquarium walls, heater, filter, etc.
Our Flourish Iron is a very different type of iron. Our's is bound to a carbohydrate that is very easily metabolized by your plants. Most of the others on the market are chelated iron supplements and your plants has to expend large amounts of energy to get the iron from the chelate to be able to use it.
If you have higher KH's in the tank's water, then you will want to use something else. Fe Gluconate is best suited for soft low KH tap water, eg, 3-4 dKH or less.
Higher, ETDA is okay, but a lot of that never makes it to the plants also, but it's not as bad as the weaker ligand Gluconate.
DTPA I think it the best for most folks with harder KH's from 3-15 etc.
I use it even with my low KH's of 1-2 dKH.
Some folks add a mix, Gluconate, DTPA and the EDTA chelators, this hits every angle/pro/con for dosing most any Tap's KH.

this will depend on what kind of Iron you are dosing, DTPA, EDTA, Gluconate etc, if you are dosing Gluconate then you will most likely get 0 on the reading after few minutes.
thanks for all the help guys,
flourish iron is FE2+ Gluconate,
im still a noob but do my best trying to understand more and more about keeping plants..
not sure what that is DTPA, EDTA``? can you guys point out another product thats would work better than or combine with Flourish iron? or is that something i have to mix my self?
another thing:
i forgot to clean the test tube yesterday after my last check were i added about 40ml iron in total and today the test tube shows color.. just under 0,25ppm
Manual says 3 min for results to show...but is this result a day after still accurate?

Testing for iron is not as simple and foolproof as many other nutrients. My iron test kit has separate methods for testing chelated and non-chelated iron. Chelated requires the addition of an additional reagent, which presumably breaks the chelation and converts it to a detectable non-chelated form.
I haven't tried testing Fe gluconate, but I hear gluconate is exceptionally stable, and that might present detection problems. Perhaps the test is successfully converting it, but at such a slow rate that you're only starting to get a reading a day later.
In any event, trust that your iron is not being consumed at such a high rate, and maintain sane dosages despite what the test is telling you.
