kiwiplymouth Posted January 29, 2012 Report Share Posted January 29, 2012 I am planning to start dosing some of my planted tanks with Chelated Iron in order to increase soluble Iron levels without using expensive products like Flourish Iron. I was just wondering if anyone else has used Chelated Iron, what the results were and what dose rates you used ? Quote Link to comment Share on other sites More sharing options...
antwan Posted January 29, 2012 Report Share Posted January 29, 2012 Yea I used to on my big planted tank and do on my current one. I can't say I noticed a difference but that's cos I started using it when I started using ferts altogether. I was told to dose 5mL/200L by Jen. Mind you I found I needed to add a lot more than the 'recommended' rate due to quite high lighting. Quote Link to comment Share on other sites More sharing options...
kiwiplymouth Posted January 29, 2012 Author Report Share Posted January 29, 2012 Awesome Antwan. Are you using the Stokers Chelated Iron? Did you test your Iron levels and if so what ppm do you aim to keep your tank at. I found this dose chart on the net. 7g in 1000ml water - dose 5ml/10gal for .1ppm 14g in 1000ml water - dose 5ml/10gal for .2ppm 21.5g in 1000ml water - dose 5ml/10gal for .3ppm 27.5g in 1000ml water - dose 5ml/10gal for .4ppm 34.5g in 1000ml water - dose 5ml/10gal for .5ppm Quote Link to comment Share on other sites More sharing options...
antwan Posted January 29, 2012 Report Share Posted January 29, 2012 Yea it's the stokers stuff. Unfortunately I don't have any test kits so can't really say I'm afraid. Wouldn't be a bad idea to invest in some though to guage what I'm using. Those levels are much higher than what I've been dosing. I have written here to use 1g per L, then dose 5ml/200L. However, I don't really have any red plants at the moment. Time for some research perhaps Quote Link to comment Share on other sites More sharing options...
kiwiplymouth Posted January 29, 2012 Author Report Share Posted January 29, 2012 The chart from the net was for 11% Chelated Fe and Stokers is 13.2% so dose rates will vary depending on concentrations but not by that much. It's not only red plants that prefer high iron levels, sagittaria for example. Agreed....its time for some more research Quote Link to comment Share on other sites More sharing options...
antwan Posted January 29, 2012 Report Share Posted January 29, 2012 Had a quick look on plantedtank.net and this was stickied about 6 months ago. It's actually pretty sweet and does all the calculations for you. You can enter it in so you dose the same amount of each nutrient but make the concentrations different (basically just to make it easier to remember), or have it however you want. Did a quick google and I believe iron chelate is EDTA Fe (13%), and that looks pretty similar to Stoker's so that's two thumbs up Quote Link to comment Share on other sites More sharing options...
kiwiplymouth Posted January 29, 2012 Author Report Share Posted January 29, 2012 According to the plantedtank.net calculator 57g EDTA Fe (13%) in 1000ml of water - Dose 20ml per 300L It's much higher than what Jen told you but I think I will give it a go and see what happens Quote Link to comment Share on other sites More sharing options...
A-town... Posted January 29, 2012 Report Share Posted January 29, 2012 apparently there is Chelated Iron in stokers trace element mix. I asked them how much but they wouldnt go into detail which is fair enough I guess. Quote Link to comment Share on other sites More sharing options...
antwan Posted January 29, 2012 Report Share Posted January 29, 2012 Yea way higher. I'll start dosing my tank according to that calculator and see how it goes. Quote Link to comment Share on other sites More sharing options...

I asked them how much but they wouldnt go into detail which is fair enough I guess. 57g EDTA Fe (13%) in 1000ml of water - Dose 20ml per 300L. This equals 1.14g Fe per dose Many of the trace mixes on the net contain 7% Fe so if stokers was similar you would need to dose 16.28g of trace mix to get the 1.14g of Fe :dunno: Quote Link to comment Share on other sites More sharing options...
Jennifer Posted January 29, 2012 Report Share Posted January 29, 2012 That liquid dosing regime was a duplicate of Flourish Iron (w/v concentration). To dose with EI you'd need to use a lot more. I use it dry, 1/4 tsp/400L every other day in addition to the trace mix which already contains iron... I think I got that dose rate from Tom Barr, but I can't recall. I have red plants and live healthy fish so I am happy. Quote Link to comment Share on other sites More sharing options...
peet Posted January 31, 2012 Report Share Posted January 31, 2012 Hi guys, just wondering where you are getting your chelated iron from?? Have you thought of mixing it into your substrate mix. Quote Link to comment Share on other sites More sharing options...
antwan Posted January 31, 2012 Report Share Posted January 31, 2012 I've just upped my ferts to that recommended by the calculator. Seems like a lot compared to what I was dosing, but we'll see how it goes. Quote Link to comment Share on other sites More sharing options...
kiwiplymouth Posted January 31, 2012 Author Report Share Posted January 31, 2012 Hi guys, just wondering where you are getting your chelated iron from?? Have you thought of mixing it into your substrate mix. You get it from here http://www.hydroponics.co.nz/ Being water soluble I don't think it would be a good idea adding it to your substrate.

amtiskaw Posted May 30, 2012 Report Share Posted May 30, 2012 Can anyone recommend a dosing rate for Stoker's trace mix? If not, I can test for iron and was thinking of dosing enough mix to get iron to recommended levels. How do people find the trace mix overall?

amtiskaw Posted July 17, 2012 Report Share Posted July 17, 2012 Bumpitty bump - anyone know the dosing rate for Stoker's trace mix? :dunno: I just got some iron chelate off them, too, so I don't want to use iron as a limiting factor when dosing the trace mix. My dwarf chain swords, which had been going great guns, started going brown. I got a small bottle of API Leaf Zone to test if iron was the issue, and that seems to have sorted it out (although I had to dose at twice the recommended rate to keep iron at EI levels), hence the Stocker's chelate.

Jennifer Posted August 7, 2012 Report Share Posted August 7, 2012 It's all a guessing game but I use 1-2 tsp of the dry trace mix per 300L every other day. I have also dosed with Iron in addition to the trace but I don't see much difference. :dunno: Quote Link to comment Share on other sites More sharing options...
