Cause and effect Dee, cause and effect, it's a matter of finding the cause in this instance <g>. If nothing else maybe I will learn something at the end of the day?

Well done - I will be very interested to see the outcome...dee Sent from my iPad On 5 Oct 2014, at 03:03, Neville <[email protected]> wrote: Just a quick update on this. I decanted and cleaned that container out *again* several days ago before returning the solution to the container. Now here it is several days later and that spot is reappearing - yet again! This is truly bizarre? BUT...!! I think I have worked out what's going on. Like an idiot I used litmus paper to check Ph - but tested it in my storage vessel instead of pouring a small amount into something else for testing. I believe the paper has released something into the solution. If paper is held in the water for just a couple of seconds a blueish mist emanates from the paper into the water, this would obviously now be a contamination introduced into the water, this also I believe is causing the milkiness as some form of compound has now developed. I'm now in the process of doing some back yard bush experimenting to isolate the problem. Another update in a couple of weeks perhaps. Have to say, if I stand on tip toe and stretch my arm really hard I can just manage to touch the bottom rung of that knowledge ladder <g>.

I decanted solution through a coffee filter {which I have never had the need to do before, and as it turns out didn't need to this time as nothing was left behind to my recollection} and wiped the bottom of vessel clean before returning solution to the same vessel from whence it came. This batch had probably been in storage for a month. I checked it the other day and that dark spot was back? I repeated the aforesaid procedure, minus the filtering. Checked again a couple of days later and that dark spot had returned yet again - What the...??? N.
