Hi GTE
I read your posts with interest, something aint right! If as you say your plate array is -+- -+- -+- does that mean that you have 3 cells with 3 plates per cell seperately? Or one cell ie? -+--+--+-? What plate gap are you using? How much water is in the container or 3 containers? A simple -+- plate arrangement with a gap of lets say 2mm between the plates and the amount of soda you say you used, should literally explode into bubble production as you are not using any neutral plates! I have done the experiment before using -+- in many formats and without neutral plates the amperage draw was colossal. Heat runaway was very quick. Maybe I missed something on one of you posts? Try and stick with baking soda in your experimantal stage....really it works! Are you sure you have ALL the leaks sealed? Cheers
