Great overview! I'm sure I'll be referencing this thread often . . . . very simple to understand. I especially like the target levels and the dosing schedule table!

To identify the specific measurements of your smidgen, dash, pinch set, a 1/8 tsp should fill a ¼ tsp in 2 tries, 1/16 tsp in 4 tries, and a 1/32 tsp in 8 tries.

John I just realized your math on this is wrong:

1/8 tsp should fill a 1/4 tsp in 2 tries: correct.

1/8 tsp should fill a 1/16 tsp in 4 tries: Incorrect.

(1/16tsp will fill a 1/8 tsp in 2 tries)

1/8 tsp should fill a 1/32 in 8 tries: Incorrect.

(1/32 will fill a 1/8 tsp in 4 tries)

Question.... I have Dry Ferts Potassium sulfate and Potassium nitrate just recieved in the mail . No instruction on how to add it to my tank . so how would I add it to my tank?

 

[Aquaticz]

hilarious post....
suggestion read thread
.

short answer - mix it or not
I suggest you use Wets calculator

http://calc.petalphile.com/

one more suggestion PACK & I mean Pack the plants in before using ferts
HTH

Thanks Aquaticz

Thanks, one question though can I pre-measure pre-mix both dry ferts KNO3 & KH2PO4 into a weekly pill holder* without it exploding or messing it up? That way I can track my 3x per week dosing better.

weekly pill holder: the container with snap lids, that has the days of the week on it to keep track of taking prescriptions.

thanks

Not sure if you got your answer yet. Yes you can mix those two chemicals together without issue. Just don't mix KH2PO4 with Fe or micros containing Fe. This combination would probably be very cloudy and the Fe would be rendered useless.

Good evening from Singapore fellow APCers.

My virgin post would be regarding EI. Have only started it a few days ago and I have a few queries.

But first, the specs for my tank
Volume: 20 gallons
Lights: 55W PL but I have another spare in case I want to increase lighting.
Planting Density: Medium (Cabomba, Christmas Moss, Dwarf Sagittaria, Anubia, Crypt and Tenellus)
CO2: Pressurized with a diffuser, purchasing a drop checker this weekend to determine if I have 30ppm but currently it's at 1bps.
Substrate: Gex Black Soil

Target doses for components;
NO3 in the form of Ca(NO3)2: 30ppm
PO4 in the form of KH2PO4: 2ppm
K in the form of K2SO4: 30ppm
Micros: LushGro Micro

Using "Yet Another Nutrient Calculator" plus some simple calculations,
It was recommended that I dose:
4.00g Ca(NO3)2
255mg KH2PO4
4.68g K2SO4

Dosing schedule would be dry dosing macros on odd days and micros on even days, off on Saturday and a 50% WC on Sunday.

My question is;
a. The Calculator suggested that I dose the above mentioned weights every other day but some people have suggested that I divide the above dose by 3 and dose a third of the weights each day. Which regime should I follow then?
b. For the Micros, contents on the Website http://www.ecocityhydroponics.com/lushgro-micros-liquid.html
puts the contents of the solution as:
Iron as EDTA chelate 21,253mg/L
Zinc 617mg/L
Manganese 5,684 mg/L
Copper 267mg/L
Boron 483mg/L
Molybdenum 471mg/L

and to dose 1 drop per 100L of water. Should I follow the instructed dosage or do I calculate out how much to dose?

Hope you guys can help.

Kindest Regards,
Ali

i mix my dry fert with ro water...I found a formula online for a 500ml container...I followed that formula but rather than using a 500ml container I used a 750ml contrainer is that ok?

depends if you used more water or not. RO water is not necessary. I use distilled water from a grocery store. If you used more water your solution is more dilute meaning you dose less fertilizer per volume of solution.

EI uses a range, if you use WETs calculator at http://rota.la you can find out where you are at with your increased volume. You may still be within EIs range. If not you most likely are within other fertilizer regiments ranges as EI is the richest dosing method I know of.

 

[kiravix]

Thank you for great topic.
Actually I want use EI and I got (NPK & TE) but I dont know how to dose because all the elements in one product, so please I need help.

My tanks 190 L & 160 L
High light
Please find the attached pictures.

I want to try EI dosing daily. But I want to premix all the ferts (except Fe) My Tank is 67 US Gal. heavily planted, photo attached. Lights 1.5 wpg 12 hrs DIY Co2 1bps

I plan to use the ferts listed in the attached file, dilute in 1000 ml distilled water and use 11 ml of the solution daily. 50% wc once a week. Last two columns are an option, i'll prepare premix either for 1 month or 3 months.

Experts please check this out and point out if i'm doing something (or everything ) wrong and suggest improvements / corrections.

 

[mistryde]

any replies please

Hey, I don't have any constructive feedback I can give you as I am a novice with the EI method...but I'm wondering how you will maintain your target ppm's with KNO3 & KH2PO4? I've been doing some research with the plants that I currently have in regards to their ideal ppm's in Nitrate and Phosphate and have found that the hardest part may lie in maintaining ppm levels.

Do you plan on just monitoring via test kits?

 

[mistryde]

Hi, I do not plan to use any test kits. Not required I was told for EI dosing

Alrighty, well...this is what I would calculate:

+/- 3/4 tsp = 3.70 ml KNO3 - x3 weekly = 11.1 ml weekly
+/- 1/4 tsp = 1.23 ml KH2PO4 - x3 weekly = 3.69 ml weekly
+/- 1/4 tsp = 1.23 ml trace - x3 weekly = 3.69 weekly
______
3.7(3)+1.23(3)+1.23(3) = 18.48 ml of ferts weekly
______
18.48 ml x4 weeks = 73.92 ml of ferts a MONTH
______
put 73.92 ml ferts in a 1000 ml bottle and then dose 35.71 ml daily for 1 month supply (based on 28 day month).

To scale up to 3 months... multiply 73.92 by 3 which equals 221.76 ml
1000 ml divided by 3 months (84 days based on 28 day month) = 11.90 ml daily

TOTAL DAILY DOSING:
---------------ONE MONTH---------THREE MONTH
-----------------35.71ml--------------11.90ml---

Does this make sense? This is how i would think to do it.

 

[mistryde]

yes makes sense, thanks

I have a 200 Gallon Planted Aquarium.

This is my current set up:

200 Gallon Planted Discus, Snails, Shrimp, Cat Fish, Long Finned Bushy Nose Plecos, and Cardinal Tetras. Aquarium consist of: 12 Panorma Pro LED Strips 8K mixed with 12K (currently at 7 hours of light per day, I reduced it to take care of an algae issue) Waiting till the end of month when the Current USA Ramp Timer Pro is released. External Eheim 2400 Hobby Pump running a Pressurized CO2 with a solenoid and with atomizer connected to a PH controller set at 7.0% AquaMaxx XL made to be a CO2 Reactor with atomizer and Dual GFO (running Purigen) / Carbon Reactor and a Coralife 18 Watt UV with a WM-P Series
Eheim 2080 Pro 3 Filter on its own line. Substrate is 3" of Flourite Black Sand. I'm in the process of changing over to using 50% RO water Right now I'm using 100% tap water filtered through a dual carbon block and media filter cartridge. Ordered the John Len Liquid Dosing Pump which was recommended by a fellow Aquarius.

These are the Ferts that I ordered, I may have ordered way too many things however I need some dosing suggestions based on my tank and what I should use and should not use. I'm planning to premix these into water and dose them with a dose timer.


Item# 4 Calcium Sulfate CaSO4, AKA Gypsum supplies calcium to plants without increasing alkalinity.
Ferrous Gluconate

Item# 1 food grade ferrous Gluconate Magnesium Sulfate

Item# 8 Magnesium Sulfate MgSO4 , This is also known as Epsom Salts Iron Chelate 13

Item# 6 Iron Chelate 13 (EDTA as chelator) , Contains 6 nitrates Mono Potassium Phosphate

Item# 10 Mono Potassium Phosphate MKP or KH2PO4 , 0-51-34 Plantex CSM + Boron

Item# 5 CSM+B Plantex a micro nutrient mix

Item# 12 Potassium Nitrate KNO3, 13.5-0-46.2

Item# 11 Macro Micro Nutrient Mix 1 lb contains 1 equal part each of Potassium Nitrate, Potassium Sulfate, Magnesium Sulfate, Plantex CSM+B.

This past week I put in Seachem Flourish Tabs for all the plants. The majority of the plants are in the sword family.

Thanks for your help in advance.

This post his about Macros only

If a Mod thinks it should be elsewhere of a separate post - please let me know

I need some help please....
I am surprised that of the many EI posts, I have yet to see one, that deals with multiple tank sizes and solutions. Mostly you see ppl posting for a certain size tank. Well I have all sizes and *think* the idea would be to calculate for the larger tank and then break that down to the number of gallons being dosed

So I thought this would be the place post what and how I mix fertilizers and how many ML of the solution I use. I am hoping a math nerd will check mixes.

I am no expert and welcome comments. I have the following sized tanks:
10 gal, 15 gal, 29 gal, 40 gal, 55 gal and a 70 gal.


I mix 3000 liters at a time.
Macro
N- target 7.5ppm using 601 g of KNO3
P- target 2. ppm using 141 g Kh2PO4
K - target 7.5 ppm using 274 g K2SO4

I use this many ML for 3 X a week for both N + P
10 gal gets 2 ml
15 gal gets 3 ml
29 g gets 7 ml
40 gal gets 10 m
55 gal gets 15 ml
65 gal gets 15 ml


I use this many ML for 3 X a week for K:
10 gal gets 6 ml
15 gal gets 9 ml
29 g gets 21 ml
40g gets 30 ml
55g gets 45 ml
65 g gets 45 ml

I think I go through to many Fertilizers???
Knowing this is EI, I will at times modify what goes in, which always seems to be more, especially with Kn03 ( otherwise I get cano BGA)
You thoughts? Thank you

 

[Diana K]

I do the same.

Q1: How many total gallons am I dosing? (Add up all the tanks)
So, how much of each material do I need for 1 week? (do some math with each dose of each material... so many teaspoons per dose, 3 doses per week...)
Put this much in the bottles (macros in one bottle, micros in the other)

Q2: How can I best dose? For me, I dose at the rate of 1ml per 3 gallons of tank volume.
So, multiply it out: How many gallons in all the tanks? How many doses in one week? (3) Divide by 3 gallons and call it ml.
Put that much water in each bottle.

Side note: I also dose with glut. I do a similar computation and add a weeks worth of glut to the bottles then top it off with distilled water. The glut minimizes the growth of 'goo' in the bottles. Per a recommendation by a chemist I also add a bit of citric acid to keep the mixture acidic.
