I have a question concerning the nitrogen cycle. I have been helping a friend to get her tank cycled and she's been having problems with lowering her nitrItes (they are always on 2.5ppm). I told her to increase the amount of water changed to 35 - 40% and she asked me a question I can't answer. She's wondering if the thing with cycling is to "build" good bacteria, wouldn't the water changes be a drawback?
Can someone here help me answer that?
