pH climbing

Post by MDB1029 »

I woke up this morning and the RA tells me my pH is 9.98.

So my first thought was my ATO dumped a ton of kalk in my system and there will be a flood of water to clean up. Well that didn't happen. So I look on the portal and it shows the pH has steadily climbed since last night at 9:00pm.

My crappy pH test kit tells me it is around ~8 and my hanna probe says it is 7.6 after calibration. T then calibrated the RA probe and it is now giving me 10.36.

So last night at about 9pm i uploaded new code with a small amount of change in it but maybe it messed up the probe?

The only things i touched were the max percentage of channel 0 and 1, and also the parameters for the lightning regarding frequency and duration and such.

Could I have done something that effected the pH probe?

Does it show the same readings if you place the probe in a cup of tank water?

Since I calibrated the probe it has started to climb faster.

I have it in tank water in a cup and it is still showing the same reading at this point.

What were the numbers you got when calibrating?

I don't remember exactly but they were something like 545 and 600. I can recalibrate and record those numbers if you need the actual numbers. The pH is 14.00 currently i think it has stopped.

Just to make sure I am calibrating correctly, does the calibration process take about 5-10 minutes? The number moves very slowly. Am I taking too long, not long enough?

600 for pH10 doesn't sound right.

That is what i thought when i was calibrating but i put it in the solution and it sat at 545 for about a minute and then jumped a couple times and then sat at 600

Does 746 sound like a correct # for the 7.0 solution on the calibration?

No. Seems your probe may need to be replaced then.
It should be around 500's for 7.0 and around 800's for 10.0

So i recalibrated again today and it was 545 for 7 and 767 for 10. However, after calibration the probe was reading 8.69 and now climbing again at 9.18 right now.

Numbers seem to be not too bad.
Is it climbing on a cup of tank water too?

Re: pH climbing

So this is what it did before

And after calibrating it today it began to rise again and then just dropped to what may be the correct pH value. I tried to get a picture of the most recent chart but my computer is one step above a paperweight and can't manage to download the image.

So it seems like it is working but i can't verify the value against anything reliable.

Is there any reason you can think of why it is doing this? Do you think the probe is the problem? of code?
