I am thinking about doing a NPS tank in an extra 40 Breeder I have laying around. I have a few questions about equipment and inhabitants. Any help would be appreciated. Specifically:
1) Should I have/do I need a fish or two to produce nutrients?
2) Lighting is obviously not a concern, but what about skimming?
3) Should I worry about a sump? Do I need enough stuff to warrant having one?
4) As far as flow goes, what are recommended flow rates, and power heads?
5) If I go no fish at all how does that change the need for things like water changes, nitrate and phosphate control, etc.?
I have two reef tanks, so I'm not new to the hobby. But this would be my first attempt a NPS tank, so I am not sure how the things I already know apply to a new biome.
Thanks.[/QUOTE

I suggest skimmerless & sumpless, if you are experimenting. Keep it simple.
Air exchange is critical in maintaining a reef without a surface skimmer that removes scum. Robust circulation at the surface will aid in gas exchange and will accelerate evaporation and cooling. Heater is required.
If you are serious, then set up a sump with a mud/cryptic refugium. IMO, never skim a tank for filter feeders. Corals are filter feeders.
Skimmers remove nutrients like free swimming bacteria that will feed the tank. All filter feeders, including corals, are nourished by bacteria & bacterioplankton.
Before you add any fish to your tank, treat it as a refugium and allow micro fauna & fana to proliferate for 90 days. I would get a large diver collected decorative live rock from the Gulf of Mexico

and have it air freighted to nearest airport. Have AlgaeBarn cultured copepods seed your tank. Get cultivated detrivores from IndoPacific SeaFarm in Hawaii. Feed your tank to grow the little people that provide food webs that recycle inorganic nutrients into organic live food of differrent sizes. In that manner, a continuous supply of live food is available.
A mature diverse sandbed will feed your system live food. Always use aroggonite as it will assist with pH buffering by providing passive alkalinity management. Most important in the sandbed oxygen and proper grain size to support micro inverts like worms, micro stars and pods. I like CaribSea “special reef grade”.
I am not a proponent of deep sandbed > 2”.
I mimic successes and to that end I suggest a reverse flow undergravel filter.
