If I want a DSB separate from my display tank what % of the display tank
should it occupy ? Is 20% in a refugium adequate to keep nitrates down?

Late reply.

I am not sure why people use % [percentage] without provide other variable.
% to what exactly?
Anyway, try to have somewhere 4in depth mininum, either in your maintank or
refugium. The area where ana type bacteria reside will need to have less to
nothing oxygen to break down nitrate to gas. This gas is the final stage
where it will float up to the surface. This will become complete natural ANN
cycle.

Use any very fine sand like aragonite ooglitic or similar. There are some
success with crush coral from some reefer. Crush Coral or gravel will trap
debris and in turn will decompose debris to release nutrient.

I was thinking % of surface area of my main tank for example if the display
tank is 1000 inches^2 Would a 6" deep 200"^2 refugium DSB make enough
difference to be worthwhile or would I need a 6" DSB in the main tank i.e.
100% DSB coverage. I will be using sugar sized aragamax

Sorry for late reply.

I would recommend 4-6in. It really depend on your tank and it enviroment.
You mostly need is the couple inches where oxygen barely reach and couple
inches where there no oxygen. This area where "ana" type bacteria will
mostly reside and break down nitrate. So in this regard, having a fine
unified sand is recommended.
