I know its variable... but If I am using the fish in method of cycling the tank (12 neon tetras) how long should it take (on average)? Its a 45 Gal tank. I know without my differences it can take from a week to a month...
Things that should make a difference:
I have a fair amount of real plants in it (6ish elodea vines, sword, small java fern, some other plant that starts with a W)
I have moved over some rocks from an already established tank.
Next question, If I have 2 filters in this tank running... can I then move an established filter to a new tank and it already be cycled?
