In one display I vaccume out the top layer of sand and replace it with new
stuff.
That tank always needs bright white sand though.

otherwise I leave it, messing with it destroys all me worm burrows.

Yep, that's correct, it's not good to vacuum the sand.

It's odd. I bought two plastic trash cans of the same size. I mix salt

Yep, that's odd, but I don't understand why you siphon water into the
other can. I just siphon mine into a drain. To make that easy, I placed
one of those stick-on thermometers on my tank with the bottom of it at
the correct location for the water level when it's 25 gallons low. I just
drain water until the water level is a little below the thermometer and
pump the new stuff in.

I spent some time vacuuming the sand. Man, it's amazing the amount of
crap (literally) that I pulled up. I'm way under my livestock limit,
but there's no lack of detritus.

Yep, there's a lot. I get the impression, though, that it's not a good
idea to vacuum the sand in a reef tank. I might be wrong there.
