So I keep a small tank for new fry, and have noticed that even if I use water from my main tank, once the tank is up for about a week, it starts a small cycle and nitrites/ammonia start to creep up.
What's the best way to avoid this? Should I keep the nursery tank filter running even when no fry are present to add to the bioload? Should I keep a couple of small fish in it to maintain the water parameters?
