So I recently did a test on my tap water and it came with ph over 8 and the aquarium co op ph stay around 6-7. The other these are very close to the api. I’m confused as to what’s going on. All my aquariums are at around 6.5 PH. I thoug of user error or no longer good chemical, so I bought I ph api test again and the results are the same again at over 8 and aquarium co op strips still show it to be 6-7
