I figured that if I'm getting more fishes, then it would be wise to start dosing the ammonia to prime the tank. So when the fishes are introduced into the tank, the bacteria is already growing to meet the higher ammonia load. I usually fill a syringe with ammonia, and inject a little into the tank throughout the day.
I still have some Salifert ammonia test kits from cycling, so I will test for ammonia in the next few days to make sure everything is fine.
Slow and steady wins the race!
