Yep, I know the feeling.
I know the owner/founder. He had the idea and got a patent on it. One test he just completed was a tug that goes from Port Angeles to somewhere in Alaska. The normally pull a gallon or more water form the trap of each tank on every round trip. Put one of these filters on one tank as an experiment. Less the a tsp in the filtered tank and over a gallon on the unfiltered. Guess which tug company wants more filters.
