I am not a big fan of sugar sand moves way too much I'd rather put crushed coral mixed with course sand 4:1 mix that being said an inch to an inch and a half is more than enough depth in that tank
Some people swear by deeper sand bed but it is a personal choice based on looks and functionality on how deep It should be
