Also, your cycle won't take long with dry rock. If you want to speed it up, add Prodibio Start Up. I add this to all new tanks that are started with dry rock. Really seems to help establish the good bacteria (rather than bad). I just add one pack (I think it has 6 or 8 vials in it) as directed until it's gone. I know the instructions say to use it longer, but one pack sure helps.
