I currently have a resun 500 but have recently acquired a red sea max 130c from a friend. Its not in bad condition but I wish to give it a good clean out to get looking as "new" possible and ready to start cycling so a can transfer everthing over from my current resun tank. If anyone has any tips or tricks on how to clean a reef tank without useing any chemicals or even info on things like useing tap water in the cleaning process? Any advice would be a big help! Thanks guys!
