I would not worry about parameters now unless you are in a super hurry to add fish; I'd recommend waiting 2-3 weeks before adding any fish. Are you doing a fishless cycle? If so, an approach that has always worked for me is to throw in a couple whole pieces of market prawn, let sit in the tank for 4-5 days, then remove. Wait a couple days and then you should be able to add fish no problem. It is when you are ready to add fish that you should focus on the water parameters.
