DIY Iron supplement

[Reefology1]

Hi, I'm unable to located Fergon tablets so I came across something I hope will work as well and wondering if I can get confirmation before I start dosing.

Heres what I found:

Each tablet has 27mg iron so if I dissolve 1 tablet in 100ml of RO/DI. The solution concentration is 270 mg/L or 270 ug/mL. Adding 1 mL to 270 L (71 gallons) of tank water will boost aquarium iron levels by 270 ug per 270 L or 1 ug/L.

Anyone see any issues?

Thanks

how about these ingredients?

 

[DrZoidburg]

Would not use this either. Can you get a hold of iron sulfate, and citric acid? Much cleaner way.

 

[Reefology1]

how about this?

 

[DrZoidburg]

Yes that with citric acid. Even iron citrate if you can find that.

 

[DrZoidburg]

Just wonder though how do you know you even need this are you testing for it?

 

[Reefology1]

icp testing regularly.

ok got the citric acid. guessing I need this because it not soluble in water?

how do I make the solution and dose it?

Thanks for all your help

also found this to make a mn supplement.

Manganese Suphate Monohydrate is 32% manganese by weight.

if I dissolve 1 gram in 1 L of RO/DI. That solution contains 320 mg of manganese, so the concentration is 320 mg/L or 320 ug/mL.

Adding 1 mL to 320 L (84.5 gallons) of tank water will boost aquarium manganese levels by 320 ug per 320 L or 1 ug/L.

If you look there is a recipe on here. The citrate makes it last in water longer. Also stabilizes it to a less toxic form.

I found this ratio https://patents.google.com/patent/DE2018229A1/en I can't find it on here yet. You may have to react the citric acid first with something like sodium carbonate. So the side reactions don't happen in your tank. This person can help also.

I selected a dose of about 0.1 to 0.3 mL of a solution containing 5 g of iron (as 25 g of ferrous sulfate heptahydrate) in 250 mL of water containing 50.7 g of sodium citrate dihydrate. This liquid is dosed 2-3 times per week to my system with a total water volume of about 250 gallons. This iron(II) citrate has turned brown and cloudy since I first made up the bottle years ago, suggesting that it is oxidizing to iron(III) and some is precipitating from solution
