Welcome to TFP!
The common PH tests will read anything below 6.8 as if it was 6.8. If your PH started below 6.8, it could be going up without any visible change in the test result. 7 lbs of PH Up in a pool that size isn't really all that much.
It is also possible for the strips to be wrong. If you can get a double check that would be good.
