Adding sand
 

My tank I already up and running and has almost an inch of sand what would be the best way of making it a deep sand bed without totally restarting ?

Are you wanting dry sand, or live sand? When I added live sand to my system, I used a piece of 3" pvc pipe, poured in the LS down the pipe kept cloudiness to a minimum, and let me put the sand where I wanted it to go. My only concern would be burying whatever creatures are in your sand bed. I would think if you did it gradually over several days it would be ok.

I was thinking live sand and that sounds like a good idea. Now if I have algea on my sand will that create a problem if it gets burried

I would do it a little at a time. Push a little bit of your existing sand up into a pile and add some new sand to the bare spot, then push the old sand back over top.

It's not a good thing to disturb a deep sand bed as it lets all the badness escape, but since your only an inch of sand I don't see a problem.

I will be moving in a couple months and will be moving this tank with me could I do it then when the tank is prett. Much empty or will it be toostressful no fish btw just corals shrimp and starfish and cuc??

just add the new sand as described above.
add in layers, to give the existing organisms a chance to inhabit and move up through the new sand.

i've done it in the past the same way.

If your going to be moving, I would wait until you have moved and then put the new sand in first in the empty tank and spread the old sand over top
