The EIS has to have had time to completely stabilize before using H2O2
and the only way to tell it has.....is to use H2O2.
So, try it on a portion of the batch, first.
If THAT reacts and goes murky, wait longer.
The murky CS won't hurt you, it just looks nasty.

How do you mean? I think it was running approximately six hours
because I forgot it was still set on manual, so was probably a bit
strong. I tested it with a TDS meter and it was about 26ppm and then
it was about 14ppm after a couple of days. dee

You didn't test the timing in a sample first.

I've made some EIS which is approximately 14ppm and left it two days

greeny grey! The amount was 500mls and I have done it before,
although only using three drops. Can anyone tell me what could have
happened? Thanks. dee
