In my 55 gallon FOWLR I currently have 4 blue-green chromis, 1 yellow tang, 1 royal gamma, 1 lawnmower blenny, and 1 small maroon clown. I will be making the change to a reef once my halides arrive in the mail. I currently am using lots of live rock ind the display and bio-balls in the sump for biological filtration. I will be taking out the bio-balls and putting a fuge in their place. Should I make the swich all at once or should I remove the bio-balls over a long period of time before adding the fuge to help keep bacteria levels in check?
