No need to rush things. It is very important to let both ammonia and nitrite drop to zero and stay there before adding any fish to the tank. the addition of the new livestock may cause another small spike if not properly cycled. It is really hard to play "catch up" with water parameters. I would test every two or three days. I know it is hard to look at an empty tank but wait it out.
Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian
