[Now that is more like it. Lots of info.
OK, new tank set up with new sand. How did you fill the tank? That will have a bit to do with how long it takes. Meaning how stirred up did it get when you filled. I know we are past this point but the best way I have found is to set a big bowl on a big plate and then run the water into the bowl. Make sense? Remember it for next time.
Could not quite tell from your answer as to if there is live rock in the tank or you are planning on getting some. If there is some it will help.
Here is what is happening. The sand is new and there are no bacteria on it. The small particles have nothing to cling to so they just swirl and swirl. If you have some live rock on the tank it will help colonize the bacteria and settle the sand storm down.
If it is really bad it could take as long as a week to clear up totally. Just wait it out. It will clear up.
The canister filter will help though. Do you know what filter floss is? It looks like the stuffing from a stuffed animal. You can buy it at the LFS but it is much cheaper from the fabric store. Just fill the canister filter with it and let it run for a few days, not too long as to start a bacteria cycle in the floss. It will definitely help clear the tank though. I just reset up my tank a week ago, all new sand, and using the bowl and plate method in combination with the filter floss in the canister it was clear in a day and half.
Hope that helps,
