I had sugar sand in my first tank had a ton of issues with it so when I upgraded I did half my tank in course sand and the other half in crushed coral both to 3/4 inch in depth and I like the look I no longer have sand all over everything and the fish/inverts that like sand can have their playground and on the crushed coral side I love the look of it and surprisingly a lot of my inverts love playing in it.
BB tanks have their advantages too but I am not a big fan of them myself but there are some damn fine tanks out there BB and are very drool worthy.
