You need to get some fish in there. Pronto. As someone else mentioned, Bio-Spira contains live bacteria. If it was a good batch, then you will have a complete "cycle" within 24 hours. However, if you don't have an ammonia source, all those good bacteria will die and you'll be back at square one, as if you had never added Bio-Spira at all.
In general, with Bio-Spira you add that plus your fish to the tank at the same time
. I'm worried that, 24 hours later, your bacteria are already dying. If you don't know exactly what fish you want to put in the tank yet, then add pure ammonia (as if you were doing a fishless cycle).
Of course, all of this could be a moot point if your tap water has sufficient levels of chlorine or chloramine, in which case the bacteria would have likely been killed anyways.
The good news is that often ambient levels of chlorine are low enough that you won't wipe your bacteria; it varies from location to location. Still, getting a water dechlorinator is the way to go. I highly recommend Seachem's Prime, which removes both chlorine and chloramine, as well as detoxifies ammonia, nitrite, and heavy metals.
If you don't mind the expense of buying another batch of Bio-Spira, then what I would recommend would be to go to the store and buy a small bottle of Prime, another dose of Bio-Spira, and a few (3-4) small fish. Come home, and...
1. Add the dechlor to the tank, stir it up a bit.
2. Add the packet of Bio-Spira.
3. Add the fish.
Of course, when I say "add the fish" I mean float the bag for ~ 20 minutes to let the temp equilibrate, then open the bag and slowly add some tank water to the water in the bag, then finally net out the fish into your tank. Never dump pet store bag water into your aquarium--all kinds of nasty stuff can get in your tank that way.
