You should be able to get it fairly easily, hydroponics is a big industry in the Netherlands. I might start with ebay?And can some please tell me where to get Fe EDDHA?
Okay, how can I figure out dosage?Hi all,
You should be able to get it fairly easily, hydroponics is a big industry in the Netherlands. I might start with ebay?

You just need the percentage iron (Fe) in the Fe EDDHA and your tank size.Okay, how can I figure out dosage?
Thank you very much Darrel.Hi all,
You just need the percentage iron (Fe) in the Fe EDDHA and your tank size.
Just for this calculation, I'm going to assume 6% Fe, 800 litres tank size and that you want 0.5 ppm (mg / L) iron.
One gram of Fe EDDHA contains 0.06 g of iron (Fe) and there are a thousand milligrams (mg) in a gram, so 0.06 g Fe = 60 milligram Fe (1000 x 0.06). Milligrams per litre and ppm are equivalent, so 1 gram Fe EDDHA in 120 litres = 0.5 ppm Fe.
We have 800 litres, so 800 / 120 = 6.67 and 6.67g of Fe EDDHA in 800 litres = 0.5 ppm Fe. You could check with Rotala Butterfly <"Nutrient Dosing Calculator"> or download the <"IFC Aquarium Fertilizer Calculator"> etc.
You might find that is a bit pink, in which case 0.2 ppm might be better, which would be 0.5 / 0.2 = 2.5 and 6.67 / 2.5 = 2.7 g FeEDDHA.

Unfortunately that is ferric (iron (III)) oxide, and <"of no use to us">.@dw1305 is it also known as FE2O3?
That is the one you want, and it is the <"one in the calculation">. Personally I'd just add 1/2 a teaspoon and that should be about right. <"FE EDDHA">Iron Chelate EDDHA 6% will this one work?
Okay, what do you think an issue?I speak from a position of a hardcore low-tech, but still...
(1) ADA Amazonia,
(2) Root tabs,
(3) Liquid Tropica complete fertilizers plus additional phosphate.
How come we are talking about nutrient deficiency? There should be a plenty of iron in the substrate -> meaning reduced iron.
Of course, high alkalinity and (additional) phosphate are iron killers. Plus an enormous sump filter.
For quite a many years, I work with RODI water only, and mineralize sparingly. That means, my waters are soft. Only sometimes, when performing experiments, I'm using moderately hard and alkaline water. I think quite many species don't do well in basic & alkaline water. Of these, some may benefit from CO2 injection (I've never tried), but others are probably hopeless.Okay, what do you think an issue?
Thank you for your feedback. Okay I will just start dosing a new solution and wait before treamming.Overall your plants don’t look too bad at all. Aside from nutrient issues, I don’t really see why rotala shouldn’t do well. It sometimes needs a while to settle before it starts to grow properly. Repeated trimming before this will just weaken the plant.
I’ve grown it in liquid rock and EI levels of fertz dosing, and our sponsor Aquarium Gardens doesn’t have any problem with similar water conditions. Although many plants are easier to grow in softer water, good flow and distribution of CO2 is key. If this is not optimal it’s usually the underlying problem.
