I understand it would be better to use sand rather than barebottom...but what if you have a power filter? Will the ray kick up sand into the power filter? Should the suction valve on the filter be modified to be higher?

I would choose barebottom anydays, unless its a display tank full of other fish and your trying to recreate a biotope.
