I agree with Ode that you need to measure the total silver in the batch using Faraday's equation. Trying to measure ionic conductivity to get ppm in this situation would be difficult if not impossible.
Using the faraday calculator, the values below give 10.65 ppm 1 gallon = 3.78 litres 10 gallons = 37.8 litres = 37800 ml 6000 milliamps = 6 amps 1 minute So, you would need 6 amps current to produce 10.65 ppm in water flowing at 10 gallons per minute. ppm = mg / L mg = ppm * L gm = (ppm * L)/1000 gm = (10.65 * 37.8)/1000 gm = .40257 So, you use .40257 grams per minute for 10 gallons Since you have 160 gallons multiply this by 16 and get 6.44 grams per batch. There are 28.35 grams per ounce, so you will get 4.4 batches for each ounce of silver... At US$13.55 per ounce the silver cost is US$3.08 per treatment for 12,500 animals... I don't think you will need polarity switching with this setup. You will have to experiment to see how much conductivity the water has: how much voltage and how much electrode surface area and how close they need to be together to get 6 amps. I think you can do this experiment with any metal electrodes to get a ballpark estimate, then do it with the silver and stainless electrodes. You may need wider electrodes (more surface area) to get this current. You could make a rectangular box for the flat electrodes with a water pipe inlet and outlet.
