I'm in the process of starting up a new 29g- the first new tank in 6 years. First time trying "silent cycle" or very short one such as described in KGTropicals.
Current tanks are 29 heavily planted SA, been going for close to 20 years, a 10 gallon planted going close to 6 years (temporarily housing way too many fish until new tank ready) and an 8 gal Nuvo Nano, (was) also heavily planted and housing some cherry barbs.

New tank cycling so far :
Substrate- ½ Eco Complete, ¼ gravel, ¼ quarter old substrate from 8 gal
Plants: from the old 8 gal and 29 gal SA, new hairgrass.
Driftwood: old small pieces from 8 gal and 29 SA, new large.
Filters: Aquaclear 20 HOB and a new Seachem Tidal 55 HOB. The Tidal 55 had been running in the old 29 gal SA for about 5 days, installed in new 29 two days ago. AQ 20 has the filter sponges from the old 8 gal in it.
Parameters: Same as other tanks atm : 0 No2, 0 No3, pH 7.5, KH 120, GH 180+

So.. Am I ready to stock? I have a couple of options, the new tank is for a breeding pair of Angels (have had them 3 mos) an SAE (a year or so) and some cherry barbs (3 mos). Put the Cherry Barbs in first, test, add the rest in a couple of days? Put them all in? Take old filter media from AQ 50 on the 29 gal SA and put it in the Tidal 55? Or is the Tidal running for 5+ days in an old tank enough seeding for the filter media?

I have a bad habit of getting caught up in minutia, lol, but did I miss anything? Thanks!

Thanks for answers. Testing is 2x per day. Not doing the fishless cycle. The ammonia will be coming from the fish themselves. The idea of using bacteria seeded (some of the sponges have been used continuously for 6 years) substrate, plants and filter media is to do the short cycle as described in KGTropicals video. Basically taking substrate, plants, and filter media from long running well established (decade?) tank, and putting it in the new one. The old sponges were installed in the new tank the same time as the fish. If ammonia spikes, there are 4 more sponges being used in old filters in the other 29 gal.
Basically I wanted to know how long the bacteria would live before the fish went in, and if used filter media, old substrate, and old driftwood theoretically would have enough bacteria to process the ammonia from 4 juvie Angels and 7 cherry barbs. At this point, the fish have been in overnight, not showing nitrite or nitrite yet, every one is zooming around begging for food.

I guess I was confuse by the question in your first post, "So.. Am I ready to stock?". I assumed that meant you hadn't put fish in yet.
Understood, I hadn't stocked when I wrote it, just checking if I'd forgotten anything before dropping them in. The fish were already in another tank, all it involved was moving them from one tank to another. I had read about the idea of not needing to cycle if the tank was preloaded with old substrate and media.
