Nuvo Int 50 Lagoon Equipment Planning

[centex99]

I'm looking for help and suggestions on all equipment for my build. I'd like to get it setup to avoid outright or do very small infrequent water changes.. Initially will setup the tank with rocks/sand and fish, then add to the corals... would like to plan most all equipment up front, but perhaps roll it out with the tank stocking...
I originally consider one of their similiar size or 60SR tanks that are AIO... but ended up going with the INT and sump route.

Tank/stand are on order, nothing else except a cheap light, rocks, and sand are currently purchased. Help me spend my money, but wisely!

Tank is the IM Nuvo 50 INT and I'm leaning towards perhaps a Trigger Systems Titanium line sump when it comes available in the next few weeks.

I am however open to suggestions on alternatives and open to not getting one with a roller, just feel it could provide lots of ease of mx.

Pump... Open to suggestions... I'll probably setup a 2 port manifold before returning it up to the tank.

With the roller would I still need a skimmer? If so, perhaps a smaller one?

I plan to have an ATO setup and am leaning towards going with Hydros for controller and future automated testing/dosing.
I'd also consider GHL... open to recommendations/suggestions/etc. I imagine, I won't need to start doing full testing/dosing until I start building up corals.

Lights... I have a cheaper chinese knock off I might use initially... but am looking for suggestions on what to use long term.

Don't have a set budget per se for any particular thing... I would rather make it nice, decently automated, and easy to maintain.

Based upon that, I'm open to all suggestions, feedback, help, etc.

I would probably look at a small skimmer and a Sicce SDC 6.0 pump to power everything. A UV is also a good idea.
