I used a Finnex HOB as a fuge, from my experience in the past with all-in-one systems, there is usually a build up that happens that would be a nuisance to clean every 2 to 3 weeks. most compartments on theses systems are 2 to 2.5 inches and 12 to 14 inches deep and it's going to be difficult to get proper water flow so the build up happens.
I suggest the Turkey Baster method every week to get the build up out otherwise when the spike hits, it's pretty extreme.
I've kept a dragonet in my 24 Pod for about 6 years before giving it away, it did fine but I did buy a pod pack to kick start the culture. It can work but you need to keep aware of your pod colony. If you're building a reef system, I'm going to assume you don't have a problem with the misc. costs that come with it.
I would rec. that you think about a HOB fuge for culturing and colonizing as well as being able to add some volume of water to your system.
Good Luck!
