For those that need to calculate the size of their pond using salt, or need
to figure out how much to add:

Salt in a Nutshell



1 lb. of salt in 1 gallon of water = 1% salinity

1 lb. of salt in 100 gallons of water = .12%

(These are "generally accepted" numbers; if you want to "proof" the numbers,
it goes like this: 1 lb. salt /100 gallons water (convert to metric) = 454
grams of salt / 378.5 liters of water = 454 grams of salt / 378,500 grams of
water = 0.001199 ppm, or 0.12%)



If there is no salt reading in the pond:

# salt x 12 / % salinity = gallons of water

Example:

25 lbs salt x 12 = 300 / .3 (salinity) = 1000 gal.



If there is an existing salt reading:

R1 = Reading 1 (existing); R2 = Reading 2 (resultant)

# salt x 12 / (R2-R1) salinity = gallons of water

Example (Say the existing salt level was .15; after salt it was .3, so the
number we're looking for is .3 - .15 = .15):

50 lbs. salt x 12 = 600 / .15 = 4000 gallons



To get # salt needed with known gallons:

(desired % / 12) x gallons of water = # salt

Example (If you want to achieve a .2% of salt in a 1500 gallon pond):

..2/12 = .01666 x 1500 = 24.999 lbs. of salt (call it 25!)



Note: If there are salt levels already in the pond, remember to subtract R1
from R2 to get your final reading; if you want a final reading of .2, but
the initial reading is .05, then the actual number you're looking for is .15
(not .2)



I hope this helps.

One of your numbers is off by a factor of 10.

If 1 lb. of salt in 1 gallon of water = 1% salinity
Then this CANNOT be correct;
1 lb. of salt in 100 gallons of water = .12%

The numbers are kinda rounded to keep it simple. By the time you extrapolate
the decimal from 1 gallon to 100 gallons, it goes up just a little bit.

Hi Lee,

Notwithstanding the impeccable source, something has suffered in the
translation :-(

I think you will find that the second statement should read;
1 lb of salt in 100 gallons of water = 0.012%

You'd better check those calculations again. 1 lb salt in 1 gallon of water
is 10.71% salinity!!!!

The amount of salt dissolved in water is termed the salinity and is measured
either as a per cent, in parts-per-thousand (ppt), or in parts-per-million
(ppm) (where 10 ppt = 1% = 10000 ppm). The more common parts-per-thousand
measurement is the weight of the salt in pounds per thousand pounds of water
(about 125 gallons). Pond-keepers often talk about the pounds of salt per
hundred gallons of water. Since 100 gallons of pure water weighs about 800
pounds, one pound of salt per hundred gallons equates to a salinity of 1.25
ppt (0.125% or 1250 ppm). (1 ppt = 0.8 pounds per hundred gallons)

The amount of salt dissolved in water is termed the salinity and is
measured
either as a per cent, in parts-per-thousand (ppt), or in parts-per-million
(ppm) (where 10 ppt = 1% = 10000 ppm). The more common parts-per-thousand
measurement is the weight of the salt in pounds per thousand pounds of
water
(about 125 gallons). Pond-keepers often talk about the pounds of salt per
hundred gallons of water. Since 100 gallons of pure water weighs about 800
pounds, one pound of salt per hundred gallons equates to a salinity of
1.25
ppt (0.125% or 1250 ppm). (1 ppt = 0.8 pounds per hundred gallons)

| Salt in a Nutshell
|
|
|
| 1 lb. of salt in 1 gallon of water = 1% salinity
|
| 1 lb. of salt in 100 gallons of water = .12%
|
| (These are "generally accepted" numbers; if you want to "proof" the

=
| 454
| grams of salt / 378.5 liters of water = 454 grams of salt / 378,500
grams
| of
| water = 0.001199 ppm, or 0.12%)
|
|
|
| If there is no salt reading in the pond:
|
| # salt x 12 / % salinity = gallons of water
|
| Example:
|
| 25 lbs salt x 12 = 300 / .3 (salinity) = 1000 gal.
|
|
|
| If there is an existing salt reading:
|
| R1 = Reading 1 (existing); R2 = Reading 2 (resultant)
|
| # salt x 12 / (R2-R1) salinity = gallons of water
|
| Example (Say the existing salt level was .15; after salt it was .3, so
the
| number we're looking for is .3 - .15 = .15):
|
| 50 lbs. salt x 12 = 600 / .15 = 4000 gallons
|
|
|
| To get # salt needed with known gallons:
|
| (desired % / 12) x gallons of water = # salt
|
| Example (If you want to achieve a .2% of salt in a 1500 gallon pond):
|
| .2/12 = .01666 x 1500 = 24.999 lbs. of salt (call it 25!)
|
|
|
| Note: If there are salt levels already in the pond, remember to
subtract
| R1
| from R2 to get your final reading; if you want a final reading of .2,
but
| the initial reading is .05, then the actual number you're looking for
is
| .15
| (not .2)
|
|

0.9 lbs of salt per 100 gallons comes out to 0.1% salt
