Well, it's good your cycling "fishless" so you'll be able to select fish based on your water parameters. I think maybe you were lucky as far as being able to add fish only 24 hours later, in the past. That reminds me of setting up a tank 33 years ago, dumping some Discus in, and then scratching my head as to why none of them did well, lol.
On the standard PH it measures 6.0 to 7.6, with 7.6 (and beyond) being bright blue. Your ph may well be 7.6, but it could also be 7.8, which you won't know since it's at the high end and the water can only get so blue.
The high range measures 7.4 to 8.8. My ph is 7.8, which is why I had to purchase the high range kit. HTH
PS. The API Master Test Kit contains both the standard PH and the high range, along with Ammonia, NitrIte and NitrAte. All tests are worth having.
