I believe pods just need an area of refuge, where flow is not too much, safe from predators. In my case, i dont use chaeto, but what i did was collect rubbles or dead sps or any stony corals and put them in a makeshift basket. See image, its on the right side, where overflow comes in.
Hmmm.... I cant remember now how to attach image from a different server. Seems, github, google drive, and reeffrontiers does not work.
