What reservoir size are people using

[velorossa22]

I was wondering what you all were using for sizes on electrolyte reservoirs? I was using 2" x 12" ABS tubing. I found I could use less KOH that way. But thinking later I'm thinking that my high heat issues could have been partly caused by being so small. I used the 2" pressure pvc cap for a lid and I found the design worked really well.
Also is anyone running dual cell stacks or 2 gen at the same time? If so are you keeping two different reservoirs feeding the 2 stacks or are you adding a T in somewhere. Where and how are the Ts done? Are you running cells in parallel or series with tubing?

I was wondering about the size of the reservoir as well. Not much room to put anything like a 3Q or 4litre container at the moment so was hoping that something smaller would be okay. Not sure about how much heat will get generated though.
Any thoughts anyone?
