That's pretty much what I did.
After a month long battle with cyano
in my 125gal I had collected more than half of a 5gal bucket of my sand with the cyano
I just dumped out the water and let the bucket sit in my garage for a few weeks.
It never got completely dried out but all the cyano
starved away and I just added it back to the tank with no problem and no further outbreak... knock on wood.
And just for the record, I also treated the tank 4 times with chemiclean over that month.
