I bought some live rock from Gulf Live Rock that I have had cycling in a container. I noticed Aptaisa on them and treated with F Aptasia killer. I checked the rocks every day turning them and looking for more. After a few weeks of not seeing any I put two rock in my sump. A couple hours later I checked them and their is two big ones flowing away. I quickly take them out and treat again with the Aptasia killer. Another couple weeks of inspecting them I don't see any and put two different rocks into my sump. Couple hours I look and two more Flowing in the breeze. I can't believe how sneaky they can be. It seems whenever I turn on the lights to check they hide from me.
