I've got an IM nuvo 8. It's very simple. Filters are readily available. Stock out of the box you should be able to keep softies. Zoas, some lps, etc. the light that comes with wont support much more than that. I've upgraded the pump, which is suggested. I've also purchased an ai nano light for mine. Can be found used for pretty decent prices. Well worth it. I've got pocci's And birdnests now. Easily supports sps now. I was topping up with store bought bottles of water just about everyday. That was getting old so I bought a tunze osmolator nano. It works like a charm. Now I only fill a small betta tank(my reservoir) under the cabinet once a week. Weekly water changes are super easy. 25% change is a large bottle of water. I would easily buy another one.
