I moved across country with my piranhas in my signature. I had to set up the tank without cycling properly because I had no choice. I tried bio-spira twice and I can't get any nitrite or nitrate to apprear. All I have is super high levels of ammonia which are out of control. Daily 30 - 50% Water changes aren't helping, it just goes back up the next day. I cut down on feeding to every third day, which is raising up aggression levels in the tank, because they are used to being fed daily. I've been here almost a month and no sign of nitrite or and anything. I have 3 magnum biowheels on my 350's and a emp 400. I've been using to prime to neutralize the ammonia, but they are still breathing heavy and itching. I gotta do something quick!! I'm burned out on water changes and I don't want to lose any fish. Comments please.
