I bought 2 used Red Sea reefer 350 set ups. They have everything including live rock, fish and coral. I’ll be breaking them down and setting them back up with in hours. It’s been 9 years since I did reef and I’m wondering what’s the best way to do this. I figured there will be some kind of cycle, but will it be as bad as setting up a new tank? I’m a bit worried about the fish and corals.
