This is from what 've read and experiance (i just recently switched)
any long term sand people feal free to add on or correct anything that sounds wrong.
if you are not careful it can mess up your filte (just turn it off whe you are adding it or stiring itt up)
you have to rinse it out really well to remove clay and whatever else
you have to stir it up to prevent the build up of harmful gasses
it looks mor natural.
corrydoras love it.
I susspect it is better for a planted tank as it is easier to root in and easier to put plants in ime
if you want colors crayola makes a brand that many people use for aquariyms they come in a small variety of colors.
If you get corydoras they sift through the sand for food in mouth out gills super awesome btw
