Thanks Lazy! I’m going to switch everything over....slowly. My plan is to move my current system to a different wall in the same room and set up the 40 where the cube currently is. Then after a long cycle to slowly move fish and corals over. I would reuse my current rock, but I have a colonial hydroid problem. So I’m going to remove my colonies from the base rock, dip, and move them into the new system. So long cycle. I’m also going to run a 25 watt emperor aquatics UV with a very slow turn over to hopefully aid in eliminating any hydroid larvae that hitchhike over.
