Well, I usually try to transplant as much yucky junk (big rocks, bogwood, ornaments, live and fake plants) into the new tank from the old tank, as that helps to get the established bacteria going in the tank. I usually add a large portion of the old water into the tank too. Yucky filters are also good for getting bacteria into the new tank, but those have to be cleaned a few days later. It's only recently that I've started using tank stabilizers like the one you mentioned, as I felt before and still rather feel that they aren't necessary--but only if you have material from an old, established tank to put into the new tank. Chemicals are probably helpful if you're starting a completely new setup.
For this tank, I actually did use much of the old water, and I did use some stabilizer, because the old tank is completely chemically out of whack. It wasn't an established setup at all because I needed a bigger tank for the fish and couldn't get one until now.
But before when I had a 55 gallon setup, I bought a 90-100 gallon used tank and made the transfer of fish and planst from the 55 to the 100. That used the same precedure I mentioned, without chemicals--established plants, wood with algae growth, and old, established water. The fastest way to get a new tank to cycle is to get long-standing, established bacteria in the tank, and this is how I've done it in the past.
Basically, you need to balance out the fish and the plants, as those are what the cycle is based around. It's best, I think, to cycle a tank with both live plants and fish, instead of just plants or nothing at all, since the cycle relies on the balance of plant byproduct and fertilization, while the fish prove the "manure" for the plants and the ammonia for the bacteria to work on.
I don't know the effectiveness of the stabilizing chemicals as I've only recently started using them. Hope that helps
