Look at this way, 35% is 350,000 ppm out of the bottle. To get to 10 ppm you need to dilute it by 35,000. There are 768 teaspoons in a gallon so it would be 1 teaspoon to 45.5 gallons of water.
We use an inline medicator. It injects 1 oz of stock solution into every gallon of water used. We would have to mix 1/2 ounce of 35% peroxide into a gallon of water to create the stock solution and then inject that at a rate of 1 oz per gallon of water to get to 10 ppm.
Thanks for explaining this one before I felt compeled to!!!
If you ever have to replace a proportioner there are 500/1 devices out there that some like better for peroxide. Do you have a reaction tank for the dosed water?
