Hey guys,
I hadn’t been monitoring my tanks properly for awhile, except for sporadically. When setting up for a new tank, I was motivated to start monitoring all tanks and discovered an ammonia spike in my oldest tank. Occupants showed no signs of distress.
Tank is 2.5 gallons and contains a Betta and mystery snail. Betta was added in May and snail was added Oct 6. I used to check tank daily and parameters never really changed as long as I did weekly 50% water changes, parameters didn’t change after adding snail.
Oct 28: ammonia 2.0, nitrite 0, nitrate 0. Did 75% water change and brought ammonia down to 1.0
Oct 29: ammonia 1.0, nitrite 0, nitrate 0. Did 75% water change and brought ammonia down to 0.5
Oct 30: ammonia 2.0, nitrite 0, nitrate 0. Did 75% water change and brought ammonia down to 1.0
Oct 31: ammonia 1.0, nitrite 0, nitrate 0.
I’m going to assume something bad happened to my good bacteria. Any recommendations on how I should handle this? I have no tank to move the guys to as new tank is still cycling and other tank has stupid aggressive betta already in it.
