    I just finished a fishless cycle using One and Only and ammonia on my display tank and quarantine tank. I added two small fish to my quarantine after a large water change to reduce the built up nitrates. In the meantime, what can I do to keep the bacteria in the display tank alive? Should I continue to dose ammonia to 2 ppm and if so, how often? My concern is that I would get a huge nitrate build-up in the display over the 4-6 weeks the first 2 fish are in quarantine.

    A small amount of fish food would work. Maybe a couple of mysis shrimp or a small piece of fish. It will break down and feed your bacteria. You dont need much. Before you start adding fish, you can do a water change if your nitrates are high.

    I would dose 0.5 ppm every few days and before you add the 2 fish check the pH and nitrate is the first is low and/or the second high do a water change.

    I would add dead fish/shrimp - just causes a mess, IMO.
