I recently set up my 240l tank. I added Nutrafin cycle and Left the heater and filter running for a week. I cut my filter media in my fluval 3 in my older tank and replaced half with half a new insert. The old half i added to my external filter in my new tank.
I then added 3 sword tails, (1 male and two females) and 3 orange platties.
Today is day the 3rd day and I performed a water test.
Nitrite between 0.3 and 0.8
Nitrate is clearly present
I'm wondering wether i need to perform a water change to dilute the nitrite and nitrate or i leave it until there is only nitrate present?
I always thought ammonia appear, got converted to nitrite then the nitrite was converted to nitrate. I have since been told that the ammonia spike can come after the nitrite. I'm a bit confused to tell you the truth.
The fish seem to be fine, no sign of stress that I can tell, they seem to be enjoying their new big home to be honest. The male swordtail is chasing the females about but nothing overly aggressive.
I believe the first sign of distress with chemical poisoning is gasping at the surface? I haven't seen that to date.
I would really appreciate a bit of guidance :)
