I filled my cell with sea water - switched on my PWM - got approx the same level of gas as tap water - left the cell for 10mins - came back and this was the result.
Accelerated algae formation? I have no idea - a murky green substance that disolved in the water.
Didn't drink it.
Still getting that light brown scum using tap water - has anyone established what it is yet?
Gazza
It is chemical reaction ... iron maybe ???
I get a similar colour from tap water and salt with certain stainless rods I have(I dont know what grade stainless as they were from scrap)... if you leave the water for half an hour or so does it settle or change colour?
when I first started with hho designs I wanted to test if letting the scum settle then filtering off the clear water would make any difference but when I tried the clear water got dirty again just as quick
I concluded that the stainless was of low grade and had some other metal like copper or iron reacting and mixing with the water
I'd be wary of using anything that would create that much gunk. I posted pics. on another thread of what my tap-water (which tastes fine) does to SS - same amount of gunk produced, but completely dissolves it in no time! I'd love to know what chemical reaction is causing that.
It would be a shame if your nice cell suffered a similar fate...
