Ammonia drops for cycle

[fishnugget1]

I have a QT tank that is fully cycled and has a sponge filter. I just removed the last fish.

Can I add ammonia drops to keep cycle going until I get a fish?

Sure

Any random amt works

One drop


Or ten, the same outcome. Even if you didn't feed they wouldn't die

Organic stores are still left
Slicks, biofilms, associated bacteria and plenty of nitrifiers all mixed in

Bac don't starve after we withhold some waste as an interval. They just hold as average population numbers on submerged surfaces
