I did some testing today using a computer power supply, and metered the aperage on the circuit while adding and changing the electrolyte solution. I am using a large vlasic pickle jar for tests, and found that ad I added electrolyte to the water it conducts a lot better proportional to the amount of electrolyte added.

In about 3L of water, I ended up with very good production with 7 tbsp of epsom salts, and 3 tbsp of baking soda.

Producing a lot of gas with 12V 15A power supply, drawing 11.40amps.
