I've made way more money off my frag rack then I spent on GFO up to this point. Plus, it's fun to grow little baby corals. Haha. Point taken though, chaeto is a lot less maintenance then glueing corals to frag plugs all day long. Plus, in a natural system, it takes care of itself and doesn't need me to change the media out monthly. Either way, he's already got a frag rack so moot point for myself.
