EI Fertilizing Made Easy

Here's my technique for making quick dosing amounts for EI ferts. It's just math really. Here's the formula:

(ml per dose desired)/(Tom Barr's dosing guidelines) * 1L H2O

Taken from his site Want more accuracy? Want daily PMDD style EI dosing? - Aquarium Plants
"60 grams KNO3
15 grams of KH2PO4
25 grams of GH booster(K2SO4 +MgSO4 may be used instead if the GH is high in the tap water)

Add 12 mls of this solution daily.
Add TMG at 2.5 mls daily.
(or you can use a mix of Fe DTPA + CMS+B, at 1:4 ratio and mix 1 table spoon to 1 liter of DI water, add HCL or Excel to prevent fungus etc)"

But change the above volumes to your new diluted/altered volume.

Dosing above is per 20 gallons of H2O

Just a really simple dilution really. TMG is Tropica Master Grow, I just use Ferrous Gluconate and CSM +B. You can DiY your own TMG but it requires MnSO4*H20 which to me is more hassle getting a hold of than it's worth to me at least.

A few notes: You're going to have to be careful with your dosing here. Don't try to make it more concentrated than Barr's formulas. They are already at near max solubility, especially with the GH booster. I had about 2-3 grams left over after doing it and I was making a more dilute solution.

Here's an example of what I did:
Taking two spray bottles and a graduated cylinder I figured out the volume of their pumps - 3.4ml.

Then I converted that into the nearest possible volume:

Macro -13.6ml
Micro -3.4ml

Just applied the ratios and then done.

A few notes:

You should use hand pumps like the kind they use for soap or hand sanitizer for this, they're more consistent and don't draw in as much air within the pump. I actually average about 3.0ml. But it's not really a big deal. I just do a few pumps extra.

Even better would be actual dosing bottles instead. But, I was too lazy so oh well- another day.

If anyone has any questions feel free to ask.

Geeze, thanks! You just saved me a great deal of work!

I've been preparing to change my dosing regimen and looking at this, but it was making my eyeballs melt, as premixing is essential for me.

I use a syringe like they use for insullin injections. I just snipped the actual needle off with a pair of wire cutters. The accuracy is spot on. They only go to 3ml though.

I used to use 1ml +- .1ml pipettes but they're frustratingly slow when you're dosing 12 ml lol. Still using for extra iron and water tests though. To me the spray bottles just make life easier. I can dose when I walk by the aquarium on my way out.

And as an addition:
You can get really high conc. HCL at a hardware store. It's used for bleaching pavement/acid etching. I just used some anti fungal I have for my pond fish. It's tetra's pond ich and fungus treatment. It contains HCL, formaldehyde and some anti microbials. 1-2ml of HCL or anti fungal is enough. Gluteraldehyde should be used in a bit larger amount if it's in excel form. Metracide should be used sparingly.

Yeah, I can see how that would speed up the process in the morning.

With Excel, I make my own by dilluting Gluteraldehyde from Cidex. The savings is incredible and it works like a champ!

Do you need GH boosters? And is the excel you guys are talking about seachem excel?

Yes, that is Seachem's Excel which is a weak solution of gluteraldehyde. Cidex and Metracide are concentrated versions of it used for fixing samples and sterilizing in labs. GH booster contains a mix of macro elements you need for a planted tank: Extra potassium, magnesium, calcium. I use Barr's GH booster because it was really really cheap. Seachem Equillibrium works the same way. I need GH booster because I use RO water which contains very little minerals in it. If you just use tap water you should get away with just a tiny bit of extra magnesium and calcium.

I use tap.. So i guess i'll just dose some magnesium and calcium. How do you make your own excel? ( mix )

I bought two half gallon jugs of Cidex online, then mixed it 50-50 with distilled water. That recipe makes a slighly higher concentration than Excel, so I dose it a little short of the recommended Excel dosage.

I know there are a lot of other ways/recipes to do it.

Correct me if i'm wrong, but i thought gutaraldehyde turns of co2 after coming into contact with water.. So if you diluted it, doesn't it render it useless?

I do not understand your what you are saying.
You might want to look at that question again and rephrase it or correct typos, etc.
What I know to be a scientific fact: Gutaraldehyde is not co2, but it does increase the available amount of co2 to aquatic plants.
With that said, the source of the Gluteraldehyde is immaterial.
Cidex and other products for sterilizing medical and laboratory equipment may become useless for sterilization if diluted, but the properies of Gluteraldehyde as a source of increase carbon for aquatic plants remains in proporotion to the amount you dose.
