I agree. This setup I stopped using and began only filling the tank with solution. I really didn’t see any difference. Either way, when the gas tank is full of holes, such as the Neptune tank, it is not possible to only fill the tank with water/solution since it just leaks out. I did try this, putting only half the tank in solution and the negative clamp outside the solution. Raises the question ….if one clamp is to be submerged, which clamp should it be?
