So just use the 6.8 water for wcs, then test with kit once its here?
I've put together some of you info, I'll answer in bold here
Since the 12th my ph has been 7 then on the 19th through 20th 7.2. Then on the 21st I checked the ph two times at different times and it was 6.8. I tested today and now it's 6.4! I know my tap water is 7.8 out of the facet. Is this worth doing a water change to try and raise it? I have also heard that low ph can cause bb to die or go dormant?
Looks like you tested partly degassed water giving you the 7.0-7.2 reading. Then did you add the driftwood? This would cause it to drop, possibly to the 6.4
I do have some wood but I soaked it before adding. I do my wc on Fridays, should I do it today instead?
What was the pH prior to adding and after adding the driftwood?
I Have some water that I let sit out since yesterday that I tested today. The ph was 6.8.
Looks like your tank is happy at 6.8 with the driftwood driving it down to 6.4, which is perfectly fine.
