Unless your sandbed has solidified into a block of cement, it's very unlikely your flow is as high as some bare-bottom tanks without causing the sand to blow around.

The short story:
Phosphate part:
A great amount of detritus and phosphate is held up in a DSB, this is held up in animals, bacteria, bacterial flock, etc,.... As bacteria cycle, they release Phosphate and take it back up, but some of it is released back into the water, then eventually re-absorbed back into a sandbed. This is where Phosphate absorbers come in to arrest some of that and reduce algae while adding iron to the system, Macro algae refugiams also do their part, but I don't see how Algae can take down nutrients to a point where algae can't use it.
Segway into Complication:
Large RDP refugiams, Phosban media, critter recharge kits, banks of additives, huge alk demand due to all the bacterial life necessary to lock up all that phosphate, for the same reason huge 02 demand.
About the "more flow in BB"
There are people around here pushing 140X turnover plus a wave box, I doubt you could do that in a DSB tank, I know I had a ruff time with 50X flow and sand.
Ill stick with my huge skimmer and massive flow, it is easer to understand and control.
Hope this answers some of your questions,

Thank you....Yes I know Sunny X has 140X.....But why can't I get high flow like BB? I use course gravel on top...fine stuff settles...
Trust me I have MEGA flow...as much as (almost) any BB'er....
You can surf on the surface waves...If I had more flow it would literally blow the shin off my acros...and that terrible ol' 4 inch DSB never moves ...yes slowly migrates but thats an added benifit of watching...A reef is ever-changing....
Like I said I like BB's but to get a BB for the more flow issue is not nessisary...

"Unless your sandbed has solidified into a block of cement, it's very unlikely your flow is as high as some bare-bottom tanks without causing the sand to blow around."
Not as high as Sunny X I'm sure, but just as high if not higher than most BB'ers....
More flow is not its (BB) advantage in my opinion....unless you had all fine sand..now that would blow in my tank..I tried fine sand...it kept it stirred in the mini tornados my tank puts out ...thats how much flow I have...literlly mini water tornados break out throughout the day...
