i was going to suggest those at first, but if a child were to grab ahold of the straps it would easily cut themJSchmidt said:I bought some of that galvanized strapping material (looks like an inch-wide piece of metal with regularly-space holes down the middle) and make two loops. I rapped a loop around each leg of the stand, near the top, and (making sure the loops were snug) attached screws to the wall behind. (Actually, it's screwed into a window sill, but the idea is the same.) It really stabilizes the tank nicely.
