It does seem like kind of a lot but if you are going sps
dominant it will help a lot. Just remember that those medias need to be changed occaisionally so that will add to your maintenance routine. I am a big advocate for maximizing water volume so the sump is a big plus, a great skimmer, diligent water changes, macro algae and maybe some gfo
I currently have a small sump (20) and a crappy skimmer (coralife) and I have 0 nitrates and .10 phosphates. I am going to converts the sump to a 40b and get a reef octopus skimmer.
What are your plans for these tanks?
