how do I figure out the analyzed numbers for a solution I made

[Green Thumb Aquatics]

--------------------------------------------------------------------------------

aside from sending them off to a lab, if I make my own liquid solution how can I get the number
an example would be flourish comp would have somethin on the side looking like this

magnesium............. .07%
maganese............... .03%
calcium................... .2%
FE iron.................... .15%

these are not the real numbers but this is the type of thing I am tryin to figure out the equation for gettin these numbers.

Hi kiineticcomfort,

You need to know the percentages in the dry ferts you are using, and how much water you are adding. If you measure using tsp, you need to know how many grams of the dry ferts per tsp. Otherwise, add the ferts based on weight in grams. It should be straightforward from there.

For example, CMS+B has about 6.72% Fe in the dry mix. CMS+B weighs about 5 g/tsp. That gives you .336g of Fe in a tsp of CMS+B. If you add 1 tsp to 450ml of distilled water, you end up with 455 g of solution (water is basically 1ml = 1g). So, .336g of Fe in 455g works out to .074% Fe. Use the same process to calculate the other micros.

Hope this helps.

ok well I have the numbers I would like for my micro solution, however for my macro I do notk so I am mixing 60 g potasium nitrate, 15 g potasium phosphate, 10 g ultimate GH boost from GLA, 8.5 g potasium sulfate, 6.5 g magnesium sulfate, into 1000 ml of water...

this is what I would like to have the numbers for ..

KNO3 contains 63.1% NO3 and 38.7% K (see Mass Percent at http://www.convertunits.com/molarmass/Potassium+Nitrate). KH2PO4 contains 28.7% K and 69.8% PO4 (http://www.convertunits.com/molarmass/KH2PO4). I'm not familiar with the Ultimate GH Boost. I see from GLA's website it contains a mix of 5 different ferts. You'll have to contact them for the ratios. Use http://www.convertunits.com/ to find the mass percentages of each item you are interested in. Do the same for K2SO4 and MgSO4. Although, I see the GH Boost already has these in it. I haven't dosed those before, to I'm not the one to speak to that.

One thing to consider: It's probably a good idea to create a separate solution of micro ferts. Something about the metals settling when mixed in with the macros. I don't recall the exact details. Mabe others more knowledgable can address that.

Hi,



If I may butt in for a moment…

First, your “solution” will never be a solution, some of things you are trying to mix do not work and play well together.:gw


There is a reason most of us divide “nutrient” dossing into “macro” and “micro” even though technically some of the nutrients may not meet the “technical” or highly precise and accurate definition.


For now let me assume that by shaking and mixing the concoction you can get even distribution so we can pretend for dosing purposes that it is a solution.


I will take you at your word that you mean to end up with an 1100-milliliter solution rather than a liter solution. Without regard to how some spreadsheet user may wish to twist and bully, 1100-milliliters are 10 percent greater than one liter. Therefore, the 1100-milliliter is approximately 10 percent more dilute than a one-liter solution.


Next, I do not know when you say you are using Potassium phosphate, whether you mean
Monopotassium phosphate KH[SUB]2[/SUB]PO[SUB]4[/SUB] (aka, potassium dihydrogen phosphate, KDP, or monobasic Potassium phosphate, MKP) or
Dipotassium phosphate, K[SUB]2[/SUB]HPO[SUB]4[/SUB] (aka phosphoric acid, dipotassium salt; dipotassium hydrogen orthophosphate; potassium phosphate), or
Tripotassium phosphate, K[SUB]3[/SUB]PO[SUB]4[/SUB], isn’t much used in the aquarium industry, I am not sure why.
Oddly enough, the little numbers in the chemical formulas can make large differences, especially when concentrated solutions or concoctions are involved.


I will assume your magnesium sulfate is MgSO[SUB]4[/SUB].7H[SUB]2[/SUB]O, Epsom salts, if you are using another hydrate I (or someone with a spreadsheet) will calculate it for you.

The person that developed Ultimate GH Booster says he “based this recipe after the popular Equilibrium product from Seachem,[SUP]1[/SUP]”. I will use the published information from Seachem.[SUP]2[/SUP]

The 1100-milliliter solution should approximately yield[SUP]3[/SUP]:

33450-ppm NO[SUB]3[/SUB]
5392-ppm PO[SUB]4[/SUB] if you are using Monopotassium phosphate KH[SUB]2[/SUB]PO[SUB]4[/SUB].
4213-ppm PO[SUB]4[/SUB] if you are using Dipotassium phosphate, K[SUB]2[/SUB]HPO[SUB]4[/SUB]
3478-ppm PO[SUB]4[/SUB] if you are using Tripotassium phosphate, K[SUB]3[/SUB]PO[SUB]4[/SUB]
28,553-ppm K if you are using Monopotassium phosphate KH[SUB]2[/SUB]PO[SUB]4
[/SUB]29,802-ppmK if you are using Dipotassium phosphate, K[SUB]2[/SUB]HPO[SUB]4[/SUB]
31,008-ppm K if you are using Tripotassium phosphate, K[SUB]3[/SUB]PO[SUB]4
[/SUB]773-ppm Ca
860-ppm Mg
10-ppm Fe


Should you choose to mix your fertz into less than 900-milliliters of distilled water, then top off to 1000-milliliters with distilled water, your solution should approximately yield[SUP]3[/SUP]:

36798-ppm NO[SUB]3[/SUB]
5932-ppm PO[SUB]4[/SUB] if you are using Monopotassium phosphate KH[SUB]2[/SUB]PO[SUB]4[/SUB].
4635-ppm PO[SUB]4[/SUB] if you are using Dipotassium phosphate, K[SUB]2[/SUB]HPO[SUB]4[/SUB]
3825-ppm PO[SUB]4[/SUB] if you are using Tripotassium phosphate, K[SUB]3[/SUB]PO[SUB]4[/SUB]
39,900-ppm K if you are using Monopotassium phosphate KH[SUB]2[/SUB]PO[SUB]4
[/SUB]41,270-ppmK if you are using Dipotassium phosphate, K[SUB]2[/SUB]HPO[SUB]4[/SUB]
42,133-ppm K if you are using Tripotassium phosphate, K[SUB]3[/SUB]PO[SUB]4
[/SUB]806-ppm Ca
882-ppm Mg
11-ppm Fe



I hope this helps, if not I apologize for butting in.

Twists & Turns Aside It Is All Simple Arithmetic

--------------------------------------------------------------------------------

Hi,

Since for whatever twisted reasons this discussion got off track from your original question, let me approach it this way.


In my last post I expressed the resultant amounts in parts per million, your question asked for parts per hundred.

1-ppm = 0.0001%
Therefore
X[SUB](%)[/SUB]=X[SUB](ppm)[/SUB]/(10,000-ppm/1%) (Edit: added ppm/1% and parenthesis so units work out, apologies for any confusion)
​

So in my above post for the 1100-milliliter solution:

• 33450-ppm NO[SUB]3 [/SUB]/10000-ppm = 3.345% NO[SUB]3[/SUB]
  
• 5392-ppm PO[SUB]4[/SUB]/10000-ppm = 0.54%, PO[SUB]4 [/SUB]if you are using Monopotassium phosphate.
  
• 4213-ppm PO[SUB]4[/SUB] /10000-ppm = 0.42% PO[SUB]4 [/SUB]if you are using Dipotassium phosphate, K[SUB]2[/SUB]HPO[SUB]4[/SUB]
  
• 3478-ppm PO[SUB]4[/SUB] /10000-ppm = 0.35% PO[SUB]4 [/SUB]if you are using Tripotassium phosphate, K[SUB]3[/SUB]PO[SUB]4[/SUB]
  
• 28,553-ppm K /10000-ppm = 2.86% K if you are using Monopotassium phosphate KH[SUB]2[/SUB]PO[SUB]4
  [/SUB]
• 29,802-ppmK /10000-ppm = 2.98% K if you are using Dipotassium phosphate, K[SUB]2[/SUB]HPO[SUB]4[/SUB]
  
• 31,008-ppm K /10000-ppm = 3.1% K if you are using Tripotassium phosphate, K[SUB]3[/SUB]PO[SUB]4
  [/SUB]
• 773-ppm Ca /10000-ppm = 0.077% Ca
  
• 860-ppm Mg /10000-ppm =0.086% Mg
  
• 10-ppm Fe /10000-ppm = 0.001% Fe

To go from parts per hundred, percentage to parts per million.

1%=10,000-ppm
Therefore
X[SUB](ppm)[/SUB]= 10,000-ppm/% * X[SUB](%)[/SUB]
​

So from your original post (SIC):

• magnesium............. .07% * 10,000-ppm/%= 7-ppm Mg
• maganese............... .03% * 10,000-ppm/%= 3-ppm maganese
  
• calcium................... .2% * 10,000-ppm/%= 20-ppm Ca
  
• FE iron.................... .15% * 10,000-ppm/%=15-ppm Fe

I hope this helps, sometimes the twists and turns are hard to follow.

thank you very much with providing me the numbers, and the math..

what in my solution in your opinion does not work?

I do use a separate micro solution, i basically mix the tropica, DIY method, with slightly higher iron as I used to use seachem and when switching my plants showed an iron deficiency because of the super large amount of iron the seachem method uses..

this is straight from tom...

To 1 liter of DI water add:

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)

and I copied it right from his post...

although I have problems gettin the GH booster disolved in the water, that seems to be the only issue and I just used his formula and tweaked it a little with the same ingredients..

Didn’t Mean To Offend, Have A Nice Life


Hi,


If you are happy, I am happy, no intention to offend.


A couple of the items won’t go into solution, a bit of uneven dosing, I do not think it matters, my advice is what it is, you know better and are certainly under no obligation to me.

I thought you asked a question, my mistake.


Sorry for butting in.

Consider the information for others.

NO OFFENSE TAKEN!!!

I honestly would like your opinion, you said the solution did not work, however in you posts I could not find where you said specifically why it would not work, I would really appreciate it if you could explain this as I have seen you posts on here and think you are a knowledgeable person

also you said you think of this to be an uneven dosing, in your opinion what would be more even? givin about the same strength...

I would really appreciate it if you could elaborate on these 2 things thanks,
Mike...
