Real World Example

I used the below method to calculate the volume of my top pond.

0.28% change = 2.8 Parts per thousand (PPT)

(17.5 lbs of salt / 2.8 PPT change ) X 120 = 750 gallons

Close to what I expected but I was still off by 200 gallons. That's a lot, about 25% off or so. That would easily make a difference if I were to dose the pond with meds while fish are in there.

It's very easy to over estimate capacity and put your fish at risk. Always know your pond capacity for emergencies.
