well aragonite and beach sand(assuming cartibean sand is from Caribbean) would raise the ph and water hardness.
which wouldn't be very good for a blackwater fish like betta.( great if it was African chicids )
Betta can tolerate it as they are quiet adaptable , but it is better to use normal silica sand.
