yes you can. i used a fluval FX6 canister on a 90g. I currently have the FX6 on 60g. Some use a hang-on filter on 40g and smaller. I advise not using the foam pad inside.

Fx6 will hold 5 1/2 gallons of water plus your media. Currently I have BRS .8 carbon and SeaChem Matrix in the trays. It's a big filter and make sure the width will fit under the cabinet. If you need me to measure mine lmk

If it's live sand, you will need to add water to it, to keep it live

You can, if that is you preference. Personally I wouldn't as i've had my fair share of tank pests and wouldn't wish it on anybody. The Dry rock will become Live Rock over time. It's also cheaper, can be sculpted to your liking and above all else.....PEST FREE. You can ask your closest LFS for a piece of rubble rock to use for seeding your tank.
