I recently upgraded my 57 rimless to a 90 and moved all my water, sand, and rock over. I used RO water for the rest of the water i needed to finish filling the tank. Its been up and running for about a week now and i tested the water yesterday and noticed im having a huge ammonia spike, its at about 2.0 ppm's. The fish and everything seem fine in the tank but i dont know if im going through another cycle or whats going on. Can someone please explain this to me.
