I was tired of wasting my rejuvinade or release me in my livewell. The directions say put one ounce per 15 gallons of water and I was always just shaking the stuff into the livewell thinking that it was an ounce. well one day I decided to measure what an ounce was and I really was putting way too much in the livewell. So this is what I did...I went to Walgreens went to the medicine area and picked up some little pill bags that close with the ziplock. I think I got 50 of the pill bags for $2.00 or so. Went home and measured out one ounce of additive and placed it in the bag and sealed it up. Now when I add some additive I just grab the little baggie open it up and pour the correct amount in. If another boat needed some it is alot easier to give them a few bags instead of your whole container. Just a quick little tip that I wanted to share.
