I haven’t used dr Tim’s, only biospira. That said, if they have similar results you can add life right away. Pods will be ok with the water, but will need something to eat. Chaeto might not do so well since you won’t have any nutrient supply in the water for it to consume yet. You’re insta-cycling your tank with Tim’s, and should be fine to add a fish or two minimum right away (depends on the tank size and bottle back size you add.). Plenty of folks have gone the bottle back route off a dry start, dropped in cuc, fish, coral, nems, etc. and took off running just fine. Not saying you should do all that, but look around, read up, and make your own judgement. I did mine with Biospira and started stocking after 5 days. I could have started immediately, but dosed ammonia just be sure. It processed 2 ppm in under 10 hours that first day.
