> I Dont believe this is plodding along in the dark. This is in a simple
form an experiment. Most aquarists dont have the ability to do assays
on water (to the fullest extent ) and must do what they can with what they have
available as did early science.
By plodding along in the dark I meant that we may know it works but we
don't know why. Some of us have some ideas but only a little evidence
one way or another.
> Any further questions Mr. UNmack???
Naah, not for the moment Rooster. :-)
