math problem.

[Flybynight]

Here is the math problem. 10 pounds or 160 oz. of Calcuim in 10,000 gallons of water will raise the calcuim level 100 PPM. My question is. I want to make a mix that is about 37,000 ppm.


How many cups, oz, or a measurement of calcuim would I need to add to a gallon of water to make the calcuim level 37,000 PPM? If you need more information just ask. I do know it is fit for human consumption.

You can use this calculator to figure it out:

http://reef.diesyst.com/chemcalc/chemcalc.html

Plugging in 1 gallon and raising Ca++ from 1ppm to 37,000ppm would require:

389.4 grams; 13.7 oz; approx 77.8 tsp of Kent Turbo Calcium

or

513.8 grams; 18.1 oz; approx 102.7 tsp of Dow Flake

I did not double check if it's correct though. It would definitely depend on what the calcium source is.

Also, I am not sure if that calculator refers to adding that TO a gallon of water or adding that amount and filling it up to a gallon. I assume the former, but it could make a difference - but probably not much in this case.

Edit: The Ca++ component of the 2 part solution from RHF (recipe 1) is 37,000ppm. The recipe for Dow Flake is 500grams or ~2.5 cups for a gallon. This is added to a container and then it's filled up to a gallon with water (i.e., a gallon of water is not added to account for the amount of calcium chloride added).

Well, that is simple. If it is RO/DI water and you are adding Kent Turbo or Anhydrous CaCl2 it will be 8,586.2 lbs for 10,000 gal of water to get 37,000 ppm Ca++. And if it was Calcium Chloride Dihyrate it would be 11,329 lbs

10 pounds or 160 oz. of Calcium in 10,000 gallons of water will raise the Calcium level 100 PPM.


Where or how did you get that ? It is way off and is 23.2 lbs for 10,000 gal to get 100 ppm using Kent Turbo or Anhydrous CaCl2. If it was Calcium Chloride Dihydrate then it would be 30.2 lbs

What Calcium additive are you using ? Why are you doing this and what is it for ?

I just want someone to use the information I give you (Here is the math problem. 10 pounds or 160 oz. of Calcuim in 10,000 gallons of water will raise the calcuim level 100 PPM. My question is. I want to make a mix that is about 37,000 ppm.) so only useing the information above. I need someone to make a formula that gives me the results I am looking for. That result is a gallon of mix that contains 37000 ppm of calcuim useing my product not dow's flake..

There should be enough knows in the information I have provided to get my desired results. The unknow verable is the product in this case. The concentrate of my calcuim is what I am looking for. On dow flake it tells you that it is 97% or what ever. I have no ideal what the concentrate is.

I know how to use the calculator you have provided. But, Your calculator only works if you use the plugs it offers. In other words, it only works if i use Dow's flake, or Dow's Peladow.

I guess I need someone to crunch the # for me because I get lost for some reason while trying to do them. Must be the sinus meds I am taking. Thanks for any help you can offer.

Well, you did not say that so you left us guessing. We are not mind readers.

Just make the math simpler.

1 lb in 1,000 gal = 10 ppm and use 3,700

3,700 / 10 = 370 x 1 lbs = 370 lbs for 1,000 gal.

370 x 10 (for 10,000 gal) = 3,700 lbs.

I need a concentrate of with 37000 PPM of Calcuim Increser. I only gave you the 10 lbs. in 10,000 = will increse calcuim 100 ppm as a refence. My goal is to have 1 gallon with 37,000 ppm of calcuim in it.


Good ideal about making it simple..

1 pound per 1000 gallons
.5 pounds per 500 gallons
.25 pounds per 250 gallons
.125 pounds per 125 gallons
.0625 pounds per 62.5 gallons
.03125 pounds per 31.25 gallons
.015625 pounds per 15.625 gallons
.0078125 pounds per 7.8125 gallons
.00390625 pounds per 3.90626 gallons
.001953125 pounds per 1.953125 gallons
.000976562 pounds per .9765625 gallons

So I take .000976562 pounds of Calcuim increser and times that by 370 and that gets me one gallon of mix with 37,000 PPM of calcuim.
I would need .361305 pounds of my calcuim increser per 1 gallon to = 37,000 PPM. I am sure that is right. Correct me if I am wrong.


Thanks for bring up Simple. NASA has this Theory called KISS. Keep it Simple Stuipd. Haha. I was thinking to big. I just needed to bring it dow a few notches. Thanks again.

.361305 pounds is equal to 5.78088 ounces

Yes

I would need .361305 pounds of my calcuim increser per 1 gallon to = 37,000 PPM. I am sure that is right. Correct me if I am wrong.


Yes BUT I would not go by that by itself and run some test. Or do the other math to be more sure

Example;

CaCO3 = 40 + 12 + 16 + 16 +16 = 100 grams. So, Calcium makes up 40 % of 100 grams or 40 grams of the 100 grams is calcium.

CaCl2 = 40 + 35.45 + 35. 45 = 111 grams. So Calcium makes up 40 / 111 = 36 % or .36 x 111 = 40 grams of 111 grams is Calcium

CaSO4 = 40 + 32 +16 +16 +16 +16 = 136 grams and 40/ 136 = 29 % and .29 x 136 = 40 grams of the 136 grams is Calcium.

All rounded off.


So all three of these yield the same amount of Calcium but the total weight of each is not the same.


Yours is the same also

40 + x+ y = ?

It appears yours is

453.59237/10 or 45.4 grams of x and 40 grams of Calcium or a total of 85.4 ~ molar weight of your ? stuff. So the Calcium makes up 46 . 8 %. It is much easier to know the molar value/mass or molecular weight of the suff in hand.

Hmm, that sounds like a odd duck and make no sense. Closest thing is Calcium(I) chloride or Calcium Hydroxide which are 75 grams. I hope you know what you are doing and not using some chemical you do not understand.


And remember people do not go by lbs or gals but milligrams, teaspoons, cups, oz, liters etc. and mg / l .

My goal is to have 1 gallon with 37,000 ppm of calcuim in it.

And just so you know 1 liter of this 37,000 ppm / gal = 37,000 ppm / l or / cup or / teaspoon or what ever.

[Flybynight]

KISS theory.. haha

You are saying that my mix is 40% calcuim?

[Boomer]

No, I'm saying there will be 40 grams of Calcium / molar weight or 40 grams of calcium in 85.5 grams of your stuff. That is 46.8 % Calcium for you mix.

[Flybynight]

I am going with Dow's Flake. Does anyone want to ship me like 5 pounds or so? Haha. I can pay pay pal. Thanks for your help. I learned lots.

[Boomer]

Go to http://www.twopartsolution.com/

So what was your stuff ?

[Flybynight]

Regal Calcuim Increser.

[Flybynight]

Thanks for the link. I had seen it before but did not remember where it was. I was going to make a post to try to find the link.

[Boomer]

Well, here is what it has in it. Now that makes a difference in things in my last calculation, which I suspeced may be in error, as I was calcualting for pure CaCl2 and it is never pure. And you would not till now tell me what it was :D

I would not be using that stuff, their CaCl2 is all over the place, 75 - 97 % :eek2: Most good stuff is from 94-97% % and Dowflake is 77-80% do to water.

It is like one day the Regal can be crap stuff and the next day good stuff. I would be willing to bet there are using anhydrous at times an dihydrate at tinmes. And you may not know which, if they don't tell you. It is for a pool so who cares.

NICE thanks for the info. I looked and looked for a dat sheet for hours with no luck. What keywords did you use to find this link? Thanks for all your research. I think I am going to trash it and get me some off that site.

[Boomer]

OK :D
