Re: Aquatic Plants Digest V4 #1330
So my question is where I can find a good quality grounding probe that does
not leak any heavy metals into the water and that can resist corrosion and,
above all, which is safe to use (e.g. no water leaking into electricity
socket via wire insulation). Does anyone know of a (possibly European)
source of good grounding probes?
Grounding probes are widely used in the reef keeping side of the hobby.
Probably any decent fish store that sells live corals will either have one
for sale or can get you one. In the US, mail order fish supply companies all
sell these. They just drop into the tank and attach to ground.
You may also want to determine the source of your stray voltage. Try
disconnecting each electrical gizmo (heater, filter,lights, etc) one at a
time and see if the pH readings stabilize. Leaking electricity from whatever
could be a safety hazard for you, so you may be better off replacing or
fixing whatever is leaking curent instead of grounding your system.
Another cause of pH drift in controllers is placement of the probe too close
to other electrical devices. You may want to play around with the location of
your probe and see if this has any effect.
Do you calibrate the controller on a regular basis? If you calibrate a
meter/controller and it doesn't hold the calibration, then that usually means
it is time for a new probe.
Hope this helps.
