what could cause a sudden ammonia rise in a cycled tank? I've been getting steady 0,0,10 readings for the last 2 weeks, but this morning I got a .5 ppm ammo reading? Just did a 70% pwc, have not added any fish in the last week, have been stocking slowly (3-4 fish per week), feeding lightly (a small pinch once daily), and I'm really puzzled by this...any ideas as to why the spike happened?
