13 ppm is the solubility limit of silver oxide. Silver hydroxide
converts to silver oxide, and back again, so this sets the limit to how
much ionic silver there can be in distilled water to 26 ppm. That means
that you reached saturation with the ionic part. Any additional amount
added has to either convert to colloid, or settle out. Over time 25 to
50% of the ionic will plate out on the colloidal particles. The silver
content remains the same, but a TDS reading will drop accordingly. I
would suspect that you had 30 ppm or higher of silver content. Adding
H2O2 to this will create a colloid containing lots of silver oxide
particles.

Well actually sol, I *did* have the generator running for about six
hours because I had forgotten that I still had it on manual. But when
I tested it with the TDS meter it only read 13 so that I took to mean
it was approx 26ppm. 2 days later, it read 7 which I took to mean
about 14ppm. I think I will dump it and start again, but it is a
waste of 500mls of my precious DW. dee

The stabilizers in the H2O2?
I wouldn't think so. I've only ever used 3% H202 from the grocery
store, and the murk doesn't happen often. It seems like if it was
additives in the H202, it would always go cloudly/murky. It doesn't.
But, I've had that murky result when the CS was really strong. I
would not have expected it to go murky if it really was only 14 ppm.
But remember silver particles do not register on conductance meters,
so maybe the CS was a lot stronger than that.
