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>.

milky with extremely strong TE, and the storage vessel had a dark spot in the
centre on the bottom.
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...???
