Im gonna switch tanks soon. I am not sure if I am gonna set up the second and let it run for a while and then transfer or just swap everything. I want to change the sand and add more live rock. How can I safely do this with minimal affect on the live stock. Im not sure if I have enough in the breaker to handle both tanks at once. IM going from a 40 to a 65 but I am also adding a bigger sump so the total water volume is gonna be around 90 gals or so. I have mostly caps montis and digis and a few other sps. Can I use live sand and add the live rock one piece here and there over time to avoid a cycle? I want to have this planed out good
