foaming problem

[Mad_Furby]

hi guys,
so i'm new to this forum, been fiddling with HHO for a while. converted an old PSU to a bench power supply last night, now i'm getting foaming problems. is it related to the amps i'm pulling?

it seems to be lots of small bubbles that are stable, so they dont burst.... result foam!
found something about anti foaming agents being good on youtube. has anyone had any problems with them? where can i get some in the uk?

has anyone come up with any other anti foaming methods... i'm a bit nervous about introducing lots of different chemicals into my KOH.

from what i can workout anti foaming is a hydrophobic... so has anyone tried WD40? any chemists think this is a good idea?

Most foaming is caused by contamination. You have to be very careful when you assemble your unit that your plates are perfectly clean.

Try draining you system and flushing it with distilled water. Refill your reservoir with clean distilled water and apply 12 volt power. There should be enough residual KOH for you to get some amp draw. Run for awhile then repeat process until you can no longer draw any amperage. Then refill with normal KOH solution (make, of course, with distilled water).

Also, excessive amperage will make foaming worse, but it usually isn't the root of the foaming problem.
