    Hi I have read all about the cycling of a new tank, but what if I am using a second hand tank that was still in operation just before I took it? I would keep the filter media within the filter, keep the gravel and take some of the water. What's the process for that?

    Thank you

    You will still need some liquid ammonia so you can see if the bacteria are still alive and working.

    Add enough ammonia to give you 2 or 3 PPM then test again after twelve hours. If there is no ammonia or nitrite present then, you're okay to stock.

    At a pinch, you could put a prawn (or some fish food, but a prawn would be better) in a bucket of water for a few days, until you get a reading for ammonia, and add that water to the tank instead of using 'pure' ammonia.
