strange pH results

[jhm]

If it was 10 or above, your pH test will give you a falsely high reading.

I can't say on the first test, but the second test last night and the one this morning were both taken with FC at 20. So if it gives falsely high readings that should explain it. That doesn't affect the R-0014 results?

The acid demand test suggested I add exactly the amount I added last night. I guess I should wait it out now until I'm done shocking since I may not be getting accurate readings.

Thanks!
