How much is in one dose of Easy Green?

[TheDojoMojo]

Hello. I have been using Easy Green for almost a year now and have loved it! I have recently been trying to figure out how much ppm of each of the nutrients (Specifically Nitrates, Phosphates, Potassium, or any other necessary nutrients that I cannot test for) is in one 1-mL-per-10-gallons dosage, as this would allow me to more accurately calculate my weekly dose according to test results/different bioload of different tanks. I have tried re-watching old Aquarium Co-Op videos but could not seem to find a suitable answer in the ones I saw. I also tried holding my own experiment in a quarantine tank but I was unsuccessful to come to a conclusion. I figured that the percentages listed on the Aquarium Co-Op website may hold an answer but I was unable to decipher the percentages into ppms. I was wondering if perhaps @Cory was able to give some info on the details inside his wonderful bottle of Easy Green, or if anyone else has personal experience in regards to this topic. Thanks!

One part per million (ppm), is equal to .0001 percent.  You can extrapolate your desired ppm knowing that base number.  I.E. 1000 ppm is equal to .1 percent, etc.

Here you go: 

NO3 - 3ppm

PO4 - 0.162

K - 2.01

Mg - 0.18

Fe - 0.034

B - 0.004

Mn - 0.01

Mo - 0.0002

zn - 0.002

This occurred to me, but then I wasnt sure how to apply the results after converting the percentages. For example, It states 2.66% N, which converts to 26,600 ppm. I know thats obviously not what's in it, but I didn't know what equation to apply to that number to find how much is in the actual dose. What would be the next step?

Thank you this is great. I'm not trying to doubt you or anything🙃, but I'm curious to know your process when finding this, or if there was a source which you found the answers from. Thanks!

It's literally listed on the website where you buy it. Scroll down, it says what is in a 10gal dose.

Medium-High Light
1 Pump per 10 gallons twice a week.

• N 2.66% , P 0.46%, K 9.21%, Mg 0.7%, S 0.80%, B 0.015%, Cu 0.00%, Fe 0.13%, Mn 0.036%, Mo 0.00%, Zn 0.072%

For optimal shelf life store out of light.

I am looking for a ppm value, not a percentage. If you know a formula with which I could convert these percentages into how much ppm are in a 1 mL dose, that would be very appreciated.

I think, for future reference, the way a % solution works is generally weight by volume, so a 2.66% solution would be 26.6 mg/ml. Once you have mg/ml, that is a straight conversion to ppm, in other words, 26.6ppm. I think your math might have crossed some units, easy to do even when you do this stuff all the time. I use this type of calculator a lot at work, it might help. It also includes a good explanation of the math. https://www.physiologyweb.com/calculators/percent_solutions_calculator.html

What I can't really explain is @Bob's numbers? So I think he means that is what you will have once 1ml of Easy Green is diluted in 10 gallons? Or?

I am lost when you converted the % to mg/mL as well as the whole weight by volume lol. Can you explain the process of turning a percent, which is equivalent to 0.0266 in decimal form, into an equivalent of 26.6 ppm, which is the same as 0.0000266 (again as a decimal).

Sorry, you are right and I am wrong.

% to mg/ml is just the definition of a weight by volume solution--1g/100ml=1% solution, because 1ml of water = 1g. So a 2.66% solution would be  2.66g/100ml, or 2660mg/100ml, or 26.6mg/ml.

My mistake was trusting google/my bleary eyes before coffee. I swear I read 1mg/ml=1ppm, which is, of course, wrong. 1mg/L=1ppm, which means yeah, 26600ppm. So I have proven that I have no idea how to convert that apparently, and spent an ungodly amount of time reminding myself of how math works.

In any case, that seems LOW to me, as you would be diluting that in 37.85L of water. Your ppm would then be 26.6mg/37.851L,  or 0.7mg/L, which is then 0.7ppm in ten gallons. That seems pretty wrong also, so I suspect either my math is still suspect (likely) or we have more chemistry to think about (also likely). I suspect the "2.66% nitrogen" is not actually the same as Nitrate, and some other chemistry voodoo is happening, that I could likely figure out if I wanted to work on this for another hour or 20, but I'm sorry, I can't, sooo....

I can say that when API's master test detects 0ppm Nitrate before ferts, and I put 1 squirt in a 10g tank that has at least some amount of water displacement by gavel and decor and stock, my test then reads about 5-10ppm. So this is something I have been also trying to figure out, and would like a real answer to. I swear I can't get my nitrates up to 20ppm to save my soul.

I should have stuck to just measuring I guess, because all I have done is confuse myself and everyone else. Apologies. But I am making API rich trying to figure it out!

Ah that makes sense. I also believe your math used to reach 0.7 ppm is correct, because I spent a bunch of time trying to figure out my own equation to solve it, and reached the same answer... which is obviously not what is actually ending up in the tanks according to a whole year of weekly API testing. So either both of us did the math wrong, or, as you suggested, there is something else going on in the chemistry of the "nitrates" themselves. I'm convinced the second one is what's happening. I ran my equation with potassium in order to see if it would seem right with a different element. My answer was 2.43, but I didnt take the time to check my math extensively. However, if this is right, then at least that sounds like a reasonable number for potassium, and at least sort of lines up with what Bob stated. This makes me pretty sure that when nitrogen becomes nitrates, something else must be going on, or maybe, the percents on the bottle mean something completely different from what I think they do. Also, a while back I asked a question on a live stream of how much ppm of potassium is in a dose of easy green, and if I remember correctly, @Candi answered my question saying 2 ppm, which is not too far off from my result, and is exactly what Bob said. I am still however extremely curious about the numbers @Bob gave us, or if he can explain something we don't know (because I still don't know what I'm dealing with😅)

And please, don't feel like you need to spend an endless amount of time on this lol. I will probably just resort to continually testing my water before and after each dose in order to get a ballpark for how many nitrates/phosphates. This will at least help me calculate my doses a little better if I run a few experiments. I tried testing on my quarantine a few times so I didnt have to account for plant uptake, but inaccuracies with testing along with a mix of other variables I couldn't really work around made me give up that method for now. If I happen to get any new info or something I will post it on this thread when I figure something out. Thanks for all the help!

It is a sickness, not being able to just keep things simple. 🙂 Like who even am I if I just follow the directions mindlessly? The nice simple, EASY directions, on EASY Green. That I bought. Because it promised to be EASY...

Yes! I have always wanted to be able to test the nutrients in my water, and do a little quick math to find out exactly how many mL I should put in to bring my levels right to the sweet spot. Easy, right? As much as I love Easy Green and the results I have had with it, this is probably one of the only criticisms I'd have of it, as many other brands like seachem give you the exact lab-tested ppm that one dose adds to your water. If I could keep all of my parameters in line perfectly I could maximize plant growth and probably do a better job of cracking down on my algae problems.😌

@TheDojoMojo these numbers from Bob came from me, directly from the manufacturer. 😀 Sorry for the delayed response from being tagged, I'm not too active here yet, as emails and youtube consume much of my time.
