I did some tests a while back with forced water circulation through the water capacitor to see if it would reduce the leakage current.
 
The leakage current was the same with and without the water circulation. Even with a pump that forced a large volume of water through the capacitor.
 
I think Meyer's circulating system reduced leakage current, but only because it pumped the water through an electrostatic filter.



you might be right on that.

I think so. I thought the circulation would reduce the leakage current so I performed the test several times. Each time my measurements were the same with and without water circulation.
 
With tap water and 12V applied I had 15mA leakage with and without circulation. Distilled was 5mA leakage with and without circulation.
 
The leakage current will vary with temperature, water type, and applied voltage.

That sounds very reasonable that the filter helps restrict current by removing contaminants. 

In my own experement I see a 30% increase in current when the pump is on.

@Hms thanks for the info on the filter!

So I was thinking about how I could build this filter when I realized I already have something very similar! If you watch my last video about pumping water through my cell you can see a PVC pipe hanging off the side of the cell with tubes hooked up to it. I built this for electron extraction experiments but it is pretty much the same thing as stans filter! in the tube is stainless steel whool. It sort of forms a capacitor because their is a positive and negative side with spacing between that gas or water can flow throught.
