Hi!
I would recommend that you put the sand in first, use a bowl and aim for it when pouring water in. It will keep the sand from going everywhere.

If it's a new tank I suggest filling 1/2 way with saltwater and then adding the sand. Stir up the sand as much as possible to eliminate any trapped bubbles in the sand. Then fill the rest of the way with more saltwater.

My method:
I fill the tank 1/2 way with water..arrange my rock first..THEN add the sand, then fill the tank with water, using something to brake the disturbing water flow like a plastic bowl or plate.

It is best to get your rock all the way down to the glass whichever method you use. This will prevent toppling rocks later.

And leave enough room to compensate for the live rock you are going to put in. Heavy live rock will mean you need less water. I'd put the live rock in after the sand settles from the above mentioned stir up, and then add the rock, then the rest of the water. That is, if you plan to have live rock.

egg crate goes in first. then the rock on the egg crate. then the sand goes in. then a plate goes in on the sand. then the water pours in onto the plate.
And yes, Flower is 100% right, with 100 people you will get 100 answers.

Or what I like to do and yes it takes some time. Go to your local hard ware store and buy some ½” pvc and ½” 90s with a clean out. You can make little tables out of the pvc its real simple. Place them in your BB tank. Then place the rock on top of the table this gives you the advantage of your rocks not being undermined by critters. You also get good advection this way. Then add enough saltwater to cover your sand bed stir as suggested. When your tank settles place newspaper over your sub straight and rock and add the remaining water slowly over the newspaper. Allow some time for settlement and slowly remove the news paper
Just my 2 cents

Newspaper?? That's news to me! LOL Don't think I like it. What about contamination from the dirty inked paper?

To add to the 100 different answers per person, IMO, the answer also varies on the size of a tank.
Something like the OP's 220gal, is going to take a couple days to fill, unless you're using tap, or have lots of premade RODI water on hand.
For large tanks (180gal+ sized systems), this is what I do.
Since depending on the complexity of the tank/plumbing/etc many like to freshwater test the system first. I fill the tank/sump/skimmer/ etc directly from my RO/DI unit. I get everything running and then add salt to bring up salinity. Let it run for a couple days, then add sand. Since it is a 220gal, unless you're planning on spending into the 4-figures for all live sand, chances are you're probably going to use dead/dried sand as the bulk of your sand quantity. I always rinse my dead sand, usually with the hose out in the yard. I add all the dried sand to the tank, and use a cup or something to slowly dump the sand in. Wait a couple days for the clouding to go down, then I add live rock. Usually this is a week-long process of ripping rocks in/out, till I get an aquascape with the rocks that I like. Then I add in the live sand to seed the sandbed.

I fill a ziplock/freezer bag with sand. Close it. Hold the bag in the tank close to the bottom. Open it slightly, and slowly dump the sand out.
I've moved my tank 4 times (once across states, other times different towns). Egg crate on the bottom, then the rock. After the moving stress is over, I go out and buy all new sand, and do the above procedure. I take my time, never had a severe sand storm that didn't clear up in a few moments.
Oh, I always used a very shallow sand bed, just enough to cover the egg crate. I knew that the moves where going to happen and I didn't want to have a sand bed that contained a substantial amount of bacteria. If the rock does most of the work, then my cycles are less severe.
