darkangel Posted December 11, 2009 Report Share Posted December 11, 2009 I have run out of Iron for my tank, but I do have lots in dry form. Unfortunately I have lost the mix ratio instructions. Need some help Jason, Werner, hint hint. Or should I just get off my but and go buy some liquid. Quote Link to comment Share on other sites More sharing options...

werner Posted December 11, 2009 Report Share Posted December 11, 2009 Plants will stockpile iron, so it's not an emergency if you're out of it. When you say dry, do you mean the trace + iron mix you get at the hydroponics place? My butt just buys the liquid (Flourish). Quote Link to comment Share on other sites More sharing options...
jvision Posted December 12, 2009 Report Share Posted December 12, 2009 If you have an iron test kit, I usually aimed for around .1ppm iron. Quote Link to comment Share on other sites More sharing options...
darkangel Posted December 12, 2009 Author Report Share Posted December 12, 2009 Would be impossible to advise unless concentration is known. It's the Iron chelate 10% in powder form. My bad, should have mentioned that. My but says get off it and go see Henry. Quote Link to comment Share on other sites More sharing options...
jvision Posted December 12, 2009 Report Share Posted December 12, 2009 Yeah.... to be honest, I used the TMG for years b/c it's so easy and convenient. I had to switch to dry when I was running the 135 on EI method b/c it got pretty expensive. But, I'd say for a 90 or less, TMG (or whatever brand you prefer) is the way to go, IMO.

jewels Posted December 13, 2009 Report Share Posted December 13, 2009 A 10% Fe product needs 0.001 grams per litre to acheive 0.1 ppm Would be nearly 1/4 gram per 75 gallons Quote Link to comment Share on other sites More sharing options...
darkangel Posted December 13, 2009 Author Report Share Posted December 13, 2009 (edited) If you have an iron test kit, I usually aimed for around .1ppm iron. I do have a Iron test kit and do tests once a week. Last 3 tests I had no readdings at all. A 10% Fe product needs 0.001 grams per litre to acheive 0.1 ppmWould be nearly 1/4 gram per 75 gallons It's a 72 gal and 1/4 gram is about what I was going to try later today after the water change.

jewels Posted December 16, 2009 Report Share Posted December 16, 2009 Last 3 tests I had no readdings at all. I have heard Fe disappears quickly. How did it go? :well: Quote Link to comment Share on other sites More sharing options...
darkangel Posted December 17, 2009 Author Report Share Posted December 17, 2009 Last 3 tests I had no readdings at all. I have heard Fe disappears quickly. How did it go? :well: Disolved a 1/4 gram and added twice, once on sunday and once today. No readings yet, but will test again each day and continue adding until I get a reading. If I have no readings in the next week I'll go back to the system I was using before. Quote Link to comment Share on other sites More sharing options...
jewels Posted December 17, 2009 Report Share Posted December 17, 2009 No readings yet Is it possible that this is a good thing? I have read that many feel iron tests are inaccurate. I have seen this explained - that because they are integrated? so quickly you may be too late to see it show up on a test. When I reach the outer limits of my understanding of the process I know that +'s and -'s are exchanged and arranged to produce a harmonious or stable state. To conform to the basic premise of the Jeopardy! format and make long gibberish short . . . is the substrate/system ready, willing, and unstable so as to accept this Fe and therefore make it undetechtable in store-bought tests ? Two questions for the price of one By the same ( & possibly incorrect ) premise- if it shows on the test have you reached (ample) saturation?

Frogfish Posted March 10, 2014 Report Share Posted March 10, 2014 Chelated iron is available at most local garden centres, not the box stores. It is called chelated iron from plant prod. A 350 gram container should go for $20 or less. 1/4 teaspoon twice a week seems to do the trick for my 65gal jungle. Instead of relying solely on the tests look at the plants, they will tell you what they need defficiency symptoms are interveinal chlorosis on newer leaves and toxicity shows up in new leaves as well in the form of pale and shriveled growth. Be careful though because many deficiency and toxicity symptoms are similar especially in micro nutrients. Quote Link to comment Share on other sites More sharing options...
