    I guess the subject says it all.

    Do not Red Plants require a little more Iron then normal green plants?

    I dose daily

    My Wisteria eats it up pretty fast. I use the Seachem Iron test and it's always showing that it vanishes after a short period of time. I also dose dry only because Seachem's Iron got too expensive for me to keep up.

    It's my understanding that the chelator used will only last for a few hours anyway. I dose dry iron once or twice a week and I don't test. I just use it EI style. I do try to dose it when the lights are on and the CO2 is good since it doesn't seem to last in the water column very long.

    Thanks to both on it and will order the dry powder stuff as right that bottle will not last long.

    So about how much for say a 125 44 and 75 gallon?

    Is there a chart to look at?

    Just use one of the online fert calculators.

    Also, read up on the different chelating agents. One is better for hard water (DPTA I believe) and one is better for soft water (EDTA I believe).

    Using dry Fe glouconate, I tend to add this to CMS+B and then DTPA Fe also.

    So I add:

    4 teaspoons of CMS
    1 Teaspoon of Fe Gluconate
    1 Teaspoon of DTPA Fe

    1 liter of hot tap water, about 20 mls of Excel
    Shake good.

    Wait 15 min, then I dose 60-90 mls to my 180, 60 mls to the 120(daily for these larger tanks if I remember, no biggie if I miss a day or two during the week) and maybe 15mls to the 70 Gal 2-3x a week(it's a lower light, slow growth/low demand tank).

    Now that sounds like a decent plan Tom.

    Ordered today.

    Fe Gluc and DTPA will last a few years for most, I got like 10lbs of each so it'll be a long time for me, but I have client's and larger tanks too.

    Um....I noticed that the chelated iron seems to last longer per the seachem test

    You may want to get a test for Iron is you're using Chelated. I noticed when I used it that the plants seem to take longer to eat it up. I had to be careful as that one seemed to not get out of the system all that fast. The FG version that Tom recommends vanishes quickly per their test but the other shows up a day or two later. I suspect my tank isn't very heavily planted but either way - I thought iron can be toxic at high amounts. Am I wrong? If yes, then hopefully someone can update and help us on this. If I'm right, then Chelated should be tested if dosing?

    Can Distilled water be used instead of Tap water?

    So I will not need to add prime to the tap water.

    Thanks
