Has anyone here done any comparison between KOH and potassium carbonate?

My S&K system came with potassium carbonate mixed one gram to one liquid ounce of distilled water. Because my duty cycles were running so high, I increased the concentration to about 2 grams per liquid ounce about a month ago. That helped quite a bit.

But now I've rebuilt me cells to a different configuration -- as recommended on this forum (see "help me fix my cells" thread under Electrodes) -- and now I don't seem to be put enough amps to produce any HHO.

I have some KOH but have been reluctant to switch because it's so caustic. But if I have to, I have to.

But before I do, I thought I see if anyone else has any experience with Potassium carbonate.

Thanks in advance for any help you can lend...
