Don't worry about pH. It flucuates naturally during the day. Don't try to dose to get it perfect. Just make sure you have a powerhead creating flow in the system and that there is a nice ripple at the water surface and your pH is fine.
And don't spend a lot of cash on cycling tests. It is more about the generals than the specifics. And if the bacteria in the tank consumed the ammonia, then it will easily test lower.
So, test today and see what your readings are. Dose up to 2 ppm
...or just throw a cocktail shrimp in some panty hose and walk away. Keep up with redosing up to 2 ppm
of pure ammonia until you get rid of 2 ppm
of ammonia and nitrite in a 24 hour period.
