I did the unthinkable over the weekend.
Montipora confusa took over my system and began to over run my acros. All attempts to slow its growth and destruction have failed. I did a complete tear down. Removed all corals, rocks, sand, and fish. All rocks will receive an acid bath today, especially the rocks that were covered with montipora. I know my actions sound extreme, because it is, I just could not take it anymore. The good news is I will finally have an opportunity to dry aquascape the system, something I really wanted to do in the beginning.
Fish and corals will stay in holding tanks until the system is fully cycled. I lost two large mille colonies almost instantly when I moved them from the system; and I am expecting to loose a few more, not to mention the high end frags.
I blame myself 100% because when I setup the 300g two years ago; I knew I had a montipora problem; to the best of my ability I scraped and chiseled every rock. This time I am not leaving anything to chance, all rock will be dried out for at least a week.
Going forward, no encrusting corals are going in the main display.
I may even go bare bottom and crank up the flow.
