Help On Cycling

Hi my husband and I are new to the fish hobby. A week and two days ago we bought six silver tiger angelfish and put them into a 40 gallon aquarium that was already set up. We have done extensive reading on how to properly cycle a tank. Unfortunately on the internet no information is the same. We want to know if during the cycle process we can try to adjust the ph levels and adjust the water clarity of the tank. Our main concern is ph levels. It is currently at a 7.2 border 7.4....the fish are eatting and swimming around no problem but we are aware that the level should be lower for the fish to thrive. Should we try to adjust the ph or just wait until the tank is done cycling? Thank you!
