setting ph

[NYreefNoob]

ok i went to jims and got some solutions to re-calibrate my ph monitor, i have a ac jr ive calibrated it 6 times and it never read's at 7. or 10. not sure what to do, the fluids should be right at 7. and 10. correct ?

While calibrating, it won't read 7 or 10. The manual explains that. After you finish calibrating, you can then dip the probe in the calibration fluid if you want to check if its correct. Then it should read the proper values.

ok i did all that and it tested out at 7. in the 7. solution, but when i put it back into sump it's reading 11.6

Does it read 10.0 after it has been calibrated and put back in the 10 fluid?

[NYreefNoob]

yes it does. ive calibrated it several times and re-check and checked it, but once i put it in the tank it goes straight to 11.6

If you are at 11.6 bottle it and sell it as drain cleaner. Something has to broken on your probe or AC JR

well it finally went down, i moved it to my dsb tank and it went after 20 min to 8.2, then put it back in other sump and it was fine, go figure

 

[NYreefNoob]

ok wtf, if i put the probe in my sump it read's off the chart, if i put in dsb tank it read's normal. not sure why

Check for stray voltage

I would bet it's the QO 3000 rick,

I just threw a QO 4000 out cause it shocked the hell out of me while doing a water change - I used it for mixing the salt water.

Same thing happened to me in the past with my QO 4000.

Too close to power head

I'm not sure if this could be the cause move the probe away from any source of magnetic fields in the tank(motors, algae cleaners etc). To test tank water put probe in container with tank water if it reads differently then something in your tank can be causing the problem. I'm not sure if the probes cable is shielded if not that can also be were the problem lies.
