i get the same thing the tank i am using 7 and 10 and my calcium reactor i am using 4 and 7 and they are both in the tank now as i am waiting for the reactor and there is a difference of .20 between the two with the 4 and 7 probe reading higher probes are both 2 months old and re calibrated a few times as i could not believe it

kind of frustrating as both my probes are fairly new. I've gone through 4 packs of the solution today already and have no more 7 left. Begining to think that it may be either a problem with the monitor or the controllor. Has anyone had issues with the Pinpoint products? My Pinpoint thermometer went for crap after 2 years.

Only have one probe (got a while back from Aqua Digital) on a Milwakee monitor. I use 7 and 10 solutions and just go back and forth between them a few times, rinsing in rodi between solutions. Settles after about 3 cycles.
How's the battery on your monitor?

you should always use 7 and 10 for your Tank PH and 4 and 7 for your Reactor PH.
You will find differences if you switch the 2 that is normal. You need to calibrate to the closest numbers to what your measuring.

More precisely, you need to choose buffer solutions that bracket your target pH. Salt water is ~ pH 8.2 so you'd choose pH 7 and pH 10 as your buffers. Your calcium reactor has ~ pH 6.5 I think and that would be pH 4.01 and 7 buffers.
