Use shavings and scoop it out. I have a 90gallon which is 48x18x24h" and there's no way in heck to move that thing when it's got anything in it. It takes 2 people when it's empty. However I'm used to 20-40sq ft guinea pig cages and various other rodents in cages that can't be moved. As well as chicks or quail in stock tanks and so on. My brooders can't be moved while full either. You just take a large cup, feed scoop, or whatever else and scoop the bedding out in to a trash bag, plastic storage container, etc... and haul it off to compost or trash.
I tried sand in my aquariums and it was horrible. The droppings sat on the top and stuck to the edges of the glass easily so it had to be cleaned every day or it looked really dirty and required a ton of scraping along the edges. The shavings will not be noticeably dirty for weeks because liquid soaks down in and the remaining dry droppings get turned over some rather than just forming lumps on the top. In the end the sand took more work and a lot more daily maintenance instead of just finding one day over a weekend to strip cages.
