jedimasterben Posted March 20, 2015 Share Posted March 20, 2015 Is the light sitting directly on your tank? Link to comment
Chrismelb Posted March 20, 2015 Author Share Posted March 20, 2015 In between the light and glass tank are pieces of clear soft tubing. These were split lengthways and pushed (cupped) onto the rim of the glass. I did this to reduce the transfer of heat to glass tank and avoid scratching light fixture. Link to comment
