cycling a filter in an established tank?
i am currently cycling my 5 gallon and in a few months ( after we move) i plan to establish a second tank by running the second filter in my current tank. how long will the filter need to be in the established tank before i can safely put it back in its own tank and add fish?
Also will it affect the already established tank?
