If you can elevate the stock tank enough that you can use the FX5 and even better, if you can add the substrate from your existing tank, you'll be in good shape. The biomedia in the filter and the substrate is coated with both kinds of bacteria to process ammonia -> nitrite and nitrite -> nitrate. You'll lose some because it's also growing on the glass and any other surface in the aquarium. But the important thing is the bacteria colony was already dealing with the bioload. As long as you don't kill it off with chlorine/chloramines, your cycle, if any, will last days.
