Sand Vs. Gravel

i love the look of sand but i had a bad first experience with it, but mostly it's to blame on the BGA outbreak i had in my former 10G betta tank. it's hard to clean BGA off sand.

in the future though, im hoping to use sand again.
 
I think sand looks better, but usually it is ugly from fish waste causing more vacs for a lean appearance.
