jp80911;3612480; said:if you used tap water straight up for the water change then the chlorine could kill off some if not all the bacterias in the filter (especially you mentioned you just did a big WC).
the other reason could be the three new fish just added. doesn't matter how long you had the tank running, you'll only have enough bacteria to support the bio load created by whatever stock you have in the tank. any additional source of bio waste will take time for enough bacterias to catch up, so it's like a mini cycle.

justonemoretank;3613328; said:I disagree with the Prime part. I use Prime in all my tanks and my pond, and never show ammonia in the tests. I use API liquid test kits. I have, however, heard this frequently about Amquel.
