Ok so I got a question. So I have a total of 3 ph probes on my tank one on my reactor one in the tank and the other in the tank but I use that to check the flow coming out of the reactor once a month. So I use the Pinpoint cal solution set the probes up and put them in the tank. One reads 7.8 and the one on the reefkeeper reads 7.98. I know for sure using 2 different ph test kits my tanks at 8.3. Could it be the cal solution? I'm worried since I have been having alk swings and the one says 6.5ph in the reactor wondering if it's reading low when it high. Any ideas??
Ph probe ?

Do you have both 7 and 10 cal solutions? did you check all 3 of your probes with the solution?
I know last time I calibrated I had to go from the 7 to the 10 and back and forth about 3 times to each until both of them read 7 and 10, rinsing the probe in RO water when going from one solution to the other

I would use calibration solution 4 and 10. It give you a better calibration. Also you should check them with 4 or 7 from time to time. Also is they won't calibrate but get close, soak the prob in solution 4 for a day or so sometimes gets it back in balance. JME.

I have used all three. I use 7 & 10 on the reefkeeper since that's what they call for and 4 & 7 on the Milwaukee for the reactor and the other just 7 since its a single set. I let them set for a sec and then adj to what # there in. I just know its saying my tank is 7.8 and I know it's around 8.3 and I have cal the probes about 3 times now
