I wonder if the definition of "cycling a tank" is actually a false concept? It's the filter that needs to colonize bacteria or cycle, not the tank.
You can probably cycle a filter without a tank, but you can't cycle a tank without a filter.
When I buy a new canister filter, I just pack half of it with media from an established filter. Then I pack the rest of both filters with some new media. I don't even think about cycling the tank.
If I had no established media, I'd probably just try to run the filter in a bucket and cycle it by adding some ammonia.
Sorry for going off the topic. I don't know anything about that bacteria starter product. Good luck and congrats with the new tanks though.
