I'm trying to improve my water as you know and the result is to add 7.1ml lactic acid to the sparge water. I looked around the house for something to measure out that small quantity without much luck. I did find a small syringe type thing my wife used to use to hand feed birds. Unfortunately it is designed for some dog medicine and is graduated in pounds for the dogs weight. It's .05ml per lb for the dog. Good luck figuring that conversion out. I did get a ball park idea and went really easy on the lactic acid.
So what should I buy to measure it more accurately?
