Wow. My ORP Probe must be way off, because I don't use any ozone. Is it even
possible to reach the levels I am reading without ozone? The probe is ran
through my Neptune Aquatroller. Maybe it is way off??

ORP is measured in mV
below 450 mV in the system with the animals
in theory, ozone leaves a residual at 450 mV...residual ozone would
do to
your animals what the residual disinfectants from your domestic/tap
water
would do (reason we dechlorinate)
however, this is theoretical; if your critters are alive and well
without
signs of scratching or respiratory distress, your level of 460 mV is
probably not above the theoretical 450 mV
basically, if you are constantly feeding ozone into your system and
you
haven't had problems with animals being affected, you probably won't
start
having problems...unless you decrease the biomass of your system or
feed
less food (less organic reduction=higher mV levels all other things
being
equal)
does your ORP analyzer/probe control the ozone feed rate in the tank
(is it
a feedback loop) or is it just measuring what is going on and you
are
manually adjusting your ozone generator?

All,
What do those of you who monitor your ORP try to keep it at? Mine is
at
about 460, and I don't know if that is good, bad or what. I have not
found
anything in my books to really help me out...
TIA,
Shane C.
