No, the easiest way to do it is put 3 oz of water in a measuring cup, pour the water into the sink and form a mental picture of how much 3 oz is. Do this once, then pour that much into the 5 gallon container before you fill it. I do this every time I fill my diesel containers.
No need for marking a baby bottle or transferring PS to a baby bottle.
Note: It doesn't hurt if you pour in more than 3 ounces into the 5 gallon container. Therefore no need for precise measurements. )</font>
Mike, sounds like you may have tended bar at some point /forums/images/graemlins/grin.gif.. I happen to agree, its not that big of a deal, as long as you are adding at least the the right amount. Too much wont hurt, just a little waste.. At $7 per bottle, no big deal..
