Sure! In your case it's about the amount of bacteria you brought over compared to bio-load (or ammonia). Say the media came from a 55 gallon which was chewing through ammo and no2
... by introducing it to a small tank, it instantly can handle the ammonia you're throwing at it simply because theres so much bacteria. We use the same basic idea when setting up QT's by introducing established bacteria from the main tank to a smaller one and having it pretty much insta-cycle. Never seen a purple shade on an API kit though, lol.
