Between work and other hobbies, my tank has been in maintenance mode for awhile now. Feeding the fish, refilling chems, and the occasional water changes has actually worked pretty well for this primarily-softies setup - all the fish and corals are healthy and growing. But the majano population has also been growing... and growing... and once they reach a certain point, occasional spot treatment isn't enough to keep them at bay. I've reached a make-or-break point, where I don't think I can stay on top of the treatment of the current plague enough to really knock them back. The plan from here is to replace as much of the rock and sand as possible, and spot-treat any majanos that sneak through the transition. I don't have the time or space to run a full temporary setup, so this reboot has to happen in-place. To minimize the risk to the existing fish and corals I'll be doing this 1/3 of the tank at a time, with each phase a few weeks apart.
