I am new to the saltwater hobby.I have just set up my tank on Wednesday 20/10/2021 I am using caribsea life rock and caribsea Fiji pink live sand. I am using instant ocean salt and I also make my own rodi water. Now that I have set up I am going to use Fritz turbo 900 to cycle my tank. But before I cycle with Fritz should my ph already be at a good range or with a new tank does ph start low and go up overtime to the proper range or do I need to do anything to change my ph before I add Fritz
