adding sand to an existing system

[BC564]

I am also going to be adding sand to a now bare bottom tank....but I was going to wait until a water change....turn off the return pump and power heads.....add the sand to my water change tub....and then syphon the water sand mixture out of the tub into the areas I want the sand....like a slurry .......I have done it before on a smaller tank and it worked very well.......
