For all of you that have stingrays. If you buy the mesh plastic screen for the center of the Magnum 350 canister filter, they fit right over the heater. use suction cups to keep them on the heater. No more burned rays. Also for a stand i used concrete blocks and a nice peice of 1 inch thick granite from the local stoneyard. you can get it cheap if u get a discolored one.
