Re: CO2 question - Recommendation on pH Probe


It's the best gadget I have ever invested in!  I now have a PinPoint pH
Controller/Monitor and love it for controlling compressed Co2.  I also owned
just the pH Monitor and never had a problem with either.  Easy to calibrate,
nice big LEDs, quality probe and nice long probe cable (I think 10").  The
probe has been in constant operation for about a year and continues to
operate perfectly but I did pick a replacement probe up on my last order at
Pet[NO "S"]Warehouse.  I keep it clean by using a tooth brush on it every
month or so and re-calibrating using pH 4.0 and pH 7.0 calibration
solutions.  For $89USD from any of the mail-order places, I pays for itself
just to be able glance over and see the current pH.  I have very soft water
and have to watch things.  Oh yea, I think I have replaced the 9v battery
once because the LoBat indicator told me to !  Pick up 3 to 4 each of the
4.0 and 7.0 calibration solution packets and your set!
