Cool!
Now I would take out the ammonia filtering pad. CAVEAT: With possible ich in the tank, you could experience fish loss while trying to properly establish your bacterial colonies by removing the ammonia pad. Get some more opinions.
You have to be feeding the bacteria colony for it to multiply and thrive. Since they apparently consumed the ammonia that the pad wasn't filtering, you may need to remove the pad so they can continue to multiply until there's enough of them to consume all the fish's waste. Otherwise you could possibly starve them back to a smaller amount, which wouldn't be good. On the flip side, you don't have your test kit yet and your fish may already be weakened.
Remember, if the ammonia number goes back up, you need to use water changes to keep it under control. Your tank will be okay, you're working on the problem, but you can't be guaranteed no losses.
I didn't respond to your thread about possible ich on your puffer because normally I would treat ich by adding aquarium salt and raising the temp, but I've never had puffers and I think they may have different salt tolerances. Plus, I'd have to look over your livestock list.
Until you get a test kit, you should probably do daily water changes of at least 25% to keep things under control without the ammonia pad. A fish-in cycle is tough... but not impossible. Don't despair, it may get worse before it gets better, but you are making progress. Hang in there.
ETA: The fish lady will be okay when she sees you'll still be buying fish from her.
