How long do mini cycles take to run their course? I have a 20 gallon long. I moved apartments, and killed some of my bacteria colony by boiling my rocks (to combat a snail infestation) and probably left my filter sponge in stagnant tank water for too long during the move. My tap water also has ammonia... .5 ppm. I did a bunch of water changes with the tap water before I realized this. This is how I think I got ammonia in my tank.... No nitrites or nitrates in the tap though though. I know I still have bacteria though. Since I'm getting nitrite and nitrate readings. So how long do you think this will take before my bacteria grows enough and breaks down all the ammonia? And nitrite Currently at .5 ppm ammonia and .5 ppm nitrite. About 40 ppm of nitrate. Can I do anything to speed the process up? I'm currently using prime to detox the ammonia and nitrite.... Thanks.
