I just got a new tank, 70g's to be exact and I'm wondering do I need to add some of the PH powder to the tank when I put the water in tomorrow? I'm going to put the water in and add stress coat then when I add the fish I'm going to add the quick start/Instant bacterial. My question is, do I add the PH powder to the tank when I put the water in or do I just leave the PH powder with the stress coat and just add the stress coat?
