I use Miracle Gro Cactus & Palm potting soil with some pre-rinsed Miracle Gro perlite.
I don't know what the rootball on yours looks like, so you may find you'll need to downsize the pot size to accommodate. If grown in lower light (I see you mentioned yours gets indirect light), the mix will need to be more porous to ensure it dries out fast enough.
Mind you, my 'Aloe Vera' summers outdoors, so I don't mix a lot of perlite into my mix for my 'Aloe Vera' because it gets a lot of afternoon sun and it dries out rather fast as it is (not that the undersized pot it's currently in helps). That said, you may need to add more perlite to your mix to keep yours more fast draining.
For cultivation purposes, they do better with as much sun as you can give them (they tend to get floppy otherwise). I don't mean stick it out in the middle of your yard for 8 hours of sun (although I suppose you could if you lived far up North,
), but Mine gets about 2-3 hours of direct afternoon sun on the West side of a patio. It actually sits a bit further back than my cacti, which receive the most sun.
