Ummmm, how far away are you toting the LR that you're adding to the tank? If it's just from a LFS minutes away, I wouldn't worry about the cycle being thrown out of whack. If that's not the case (and the new stuff is pretty purple for having been shipped), and you had the rock shipped, yeah, that might cause a spike in the water from die off that occurs during the shipping process. If the latter is the case, maybe you could scoop the clowns out of the tank and have another SW keeper friend hold them for you, or perhaps ask your LFS to keep them for you. A reputable LFS will certainly do that for a potential return customer. Either way, since you've not seen a cycle yet, temporarily rehoming your little clowns and throwing an uncooked shrimp in might be your best bet yet. Best of luck to you!!
I think your tank is looking awesome. Can't wait to see everything unfold for you.
