is there anything i can do to keep sand from scratching up my glass? how much sand is neccesary?can i put sand some in my sump tank? is there an option other than sand, i have 100 pounds of live rock. thanks

one of the reasons im setting up a new tank is my old one got scratched up with the mag float.its not that hard if you get to close to the sand
