I hope one of those numbers is a mistake, or you need to get all the fish out NOW. Nitrites should be at 0. Nitrates are on the high side but on its own that wouldn't kill your fish so quickly.
7 days is not nearly enough time to cycle a tank without fish in it from start. If you had starter medium (gravel or filter media from a cycled tank) then 7 days would be enough time, but if you are starting with new substrate new filter, 7 days won't do much. The first phase usually takes about 2 weeks, for the bacteria to even begin growing.
Nitrities at 30 must be wrong, but if it is higher than 0 it will quickly kill your fish, all of them.
Sorry, this sounds very much like I'm scolding you. I was just shocked to see that number. If your nitrite reading is above 0, that is your problem. If you started to cycle and then added fish, it probably made your tank go crazy. I would take out all the fish (sorry, I dont remember if you have any left), do a big water change, and continue with the cycle before putting fish back in. Like I said, a fishless cycle takes longer than 7 days, it will take closer to 4 weeks.
