    Hi,

    Not anymore. :)

    Yes. :eek::eek:

    250 ml Distilled Water + 24 grams

    Hi,

    Assuming your dry Ferrous Gluconate is the same as mine. ;)

    For a stock mixture:
    Into 250 ml of distilled water 24 grams (heavy 2 teaspoons) of ferrous gluconate powder.
    This will yield something over 10,000-ppm Ferrous Gluconate solution (a bit stronger than Seachem Flourish).
    Store in a dark container, Hydrogen Peroxide bottles are great.
    Each milliliter added to 15 gallons (38 liters) will add a little more than 1-ppm to the water colunm.

    If you prefer a little more control over the dosage either double the distilled water or halve the Ferrous Gluconate powder so that the solution will be 5000-ppm and each milliliter added will raise the iron 0.5-ppm. :cool:

    Hi dannyfish,
    0.45g Fe Gluconate (1/16tsp dry) will give you 1ppm when added to 15 gallons of water. Bio and Wet are using different numbers for Fe Glucconate -- Wet around 12.46 % Fe and Bio is using 11% Fe. Wet knows this and believes Bio is correct to use the 11% but the difference is not much really. Add it dry or add it to some tank water first before adding it to your tank, if you like. Stock solutions work well for smaller tanks and lighter doses.

    Biollante and a few others on this site have a sharp pencil. I would take the advice of a cogitator over a calculator every time. However, I have found a collection of calculators that are great time savers. This is one of them, Yet Another Nutrient Calculator, http://calc.petalphile.com/

    If you decide to make a stock solution and run into mold/bacteria add a little HCL to the DI water or 25 mL Excel per 1000 mL. Do this first, then add the dry powders (Fe) after 5 minutes or so. Personally, I use 0.5g Ascorbic Acid & 0.2g Potassium Sorbate to a 500mL stock solution to keep out mold.

    Hi,

    I have clear pump bottles for all my solutions, micros , macros and Excel/Metricide . Do the bottles have to be dark ? Where the heck do I find/purchase dark pump bottles? Darn, I just bought the clear pump bottles 2 wks ago.

    Since Tug figured out that 1/16 of a teaspoon is 1 ppm in your tank, I would just dump the 1/16 teaspoon dry into your tank once per day. I dose iron everyday since it doesn't stay available to the plants for very long. You can get a set of baking teaspoons labeled, dash, pinch and smidgeon. The pinch spoon equates to 1/16 of a teaspoon. I add a dash per day (1/8 teaspoon) in my 46 gallon bowfront and no issues. I have Red Cherry Shrimp, Cardinal Tetras and Hengels Rasboras and they don't seem to mind. I do at least one 50 % water changes per week.

    Well, maybe just a smidgen once a day. Depends on actual water column, plants, type of substrate, KH, etc.
    So, one smidgen = 1/32tsp. Very cool. I learned something today. Thanks hbosman.

    Hi Tug, All,

    Generally the calculators will easily be more precise than I am, for my own purposes I do most arithmetic in my head. For the forum I use pencil and paper or more likely dry erasable marker and white board. I rarely go more than 2 significant digits, for my own use I seldom bother with that level of accuracy. :)

    I round off a lot use proportions and generally do not think a variance in answer of plus or minus 5% is going to make a particular difference, given inaccuracies inherent in our measuring, estimation of water volume, biomass and purity of the chemicals we are using.

    I get the calculators give people these ridiculously accurate answers in to parts per quadrillion, I just do not think our real world limitations make those numbers meaningful and in many cases are terribly misleading.

    I do think it is worth knowing how the numbers are derived. :)

    Personally I find most calculators tedious, I will credit Wet with having about the best no nonsense calculators around.

    Barbarossa give the clear bottles a try I suppose...

    There was a discussion sometime back regarding how NO3 was calculated on one of the major calculators, some asked me to write out the way I would solve the problem, I went out 3 significant digits here. For what it is worth.

    >Well there used to be an image here, I waz informed forces of unimaginable evil had blocked the image and obviously it is true, for those interested the link is

    Undoubtedly just another of the 1% in their pursuit of money, trying to crush the hopes, dreams and spirit the 99%! Dastardly!

    Ok! You have me curious. I have a 46 gallon bowfront and run pressurized CO2 until the drop checker turns yellow. I burn 2x39 watts of T5HO bulbs 9 hours per day. I dose KNO3 dry with a dash spoon (1/8 of a teaspoon). I dose 4 dashes (.5 teaspoons) on water change day once per week. The fertilator says that's about 10.53 ppm per week. I input 40 gallons into the fertilator.

    What would your calculations estimate?

    Close Enough

    Hi,

    I would does at least once again mid-week. :D

    This is a little unfair since KNO3 is so common I have it about memorized. Knowing that NO3 makes up about 61% of KNO3.

    Just “eyeballing” the numbers, I made it to be about 10-ppm NO3 since half a teaspoon of KNO3 is about 2.5 grams (based on the numbers you provided it is obvious Fertilator uses 2.6 grams) and conveniently (and obviously) 60 % of 2.5 grams is 1.5 grams NO3 equally conveniently 40 US gallons is about 150 liters so we have 1500mg of NO3 into 150 liters (I know it is actually 151.4 liters) that is 10-ppm NO3. :)

    Calculating using the more accurate 61% NO3 in KNO3 and using 2.6 grams to the half teaspoon yields 1.59 grams of NO3 into 151 liters 10.53-ppm NO3. Close enough I think. :eek:

    Rahter than need to use dark bottles can't you just put the bottles in a dark cupboard? Mine are all in clear 'ex tropica' bottles :) in the cupboard under the tank.

    On the Ferrous Gluconate, anyone have an idea where to get dry powder in the UK. All I can find are iron pills which also contain all sorts of other things. They contain Ferrous Bisglycinate but all brands have vitamins added and this and that with it.

    dannyfish,
    I understand you have both Seachem iron and the Fe Gluconate powder. You should know they use the same chelate. There is no real benefit from dosing both Seachem and the Fe Gluconate powder. Adding iron with different chelates/ligands would be more advantages, http://www.barrreport.com/showthread.php/6930-How-long-iron-gluconate-quot-live-quot-in-tank

    FYI, a calculator for Seachem products (http://www.fishfriend.com/fertfriend.html) finds about 3 mL of their product is all you need for a daily dose.

    AC, http://www.aquariumfertilizer.com/ sells and ships anywhere in the world. You know that. Maybe someone will know of a dealer closer to you. Try http://www.ukaps.org/

    I dose two pinch every week on a 90 gallon tank.
    I know it does not stay good very long but I dose a complete trace product every day and plants have a least one day in the week when the can eat iron until drop :)

    I mix it with some water in a beker before I add it to the tank.
