It looks to me as though nitrite is at 5ppm, which means, in reality, it may be considerably higher as that's the limit of the test. Nitrate in the tank is higher than the tap water so some nitrite conversion is happening. This will continue, slowly at first but then more rapidly as the colony of nitrite eating bacteria expands. You may not see a drop in nitrite on the test as it will take a while to get down below 5ppm, but nitrate should continue rising to give an indication that things are proceeding. I would estimate you have about a week to go.
