if your planning alot of flow, a remote DSB in the sump is alright and doing the main tank bare bottom. crushed coral substrate traps debris and detritus and isnt the best choice IMO. your going to def. want a skimmer, i suggest reading online reviews on different brands/models as some are garbage and others golden.

The skimmer is not optional. It is not a piece of equipment that you should even consider skipping. It does not compete against the DSB, but rather compliments it. The denitrification ability of the DSB is most effective when the amount of organics are reduced to near zero by the skimmer.

Jason, Hi again, a DSB is a fairly efficient mechanism for consuming nitrates and phosphates it is however a "closed circuit" and does have limits, without a protein skimmer it will have a much shorter life span.
As for flow, this is a an area you need to research, as an example my tank about 100 gal, I run 2 1500 gph pumps as returns and a prop drive power head, flow can be turn over, # of times it goes thru the sump per hour, laminar flow is just like power heads moving water.
Sand beds dont fly around because after a very short time it gets gunked up a bit, so seriously LOCK up you wallet and SPEND some time on researching, this is a BIG tank, it will consume big money and the worst money spent is on stuff that dosent do what you need.
Start a list of what you want to keep, find out what they need to thrive and equipment will fall into place, keep asking questions thats what these boards are for
