Okay, I'm a little confused about A/N/N in cycling a tank and curing live rock. Here's what I "think" I know: when cycling a tank the amonia levels will get really high then turn into nitrites then nitrates so you dont want to do water changes during cycling in order to get these levels up. But when curing live rock you want the Amonia and Nitrites levels to read 0 but you are supposed to do 50-100% water changes every other day? I don't get why you would do water changes when curing but nt when cycling. Is it because when you do water changes during curing you are "washing away" the things that are causing the amonia and Nitrites levels to go up? Sorry for the long post and for the "ignorant" questions.
