Cycling - Ammonia

[Tetra]

It's a good idea to keep the ammonia test. Should something go weird in your tank it is good to check if you have ammonia in there. Sometimes things happen (forgetting to put dechlorinator in the water before adding, accidental exposure to cleaning products or aerosols....) and you could lose your bacteria. Then the ammonia would show in your tank and you'd know to do a water change and to prepare yourself for having to do another cycling of the tank!

Congratulations though on the fast progress with your tank!!!
