Salt in a Nutshell
You'd better check those calculations again. 1 lb salt in 1 gallon of water
is 10.71% salinity!!!! Dean Markley "Lee B." wrote in message ... 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.
