I'm not sure how your tank looks, but I have an Oceanic 72 G RR tank and it has the plastic canopy. I plan on laying the Cool Touch canopy on top of the plastic canopy. It does come with some metal chains that would allow you to hang them from the ceiling, but I live in an apartment, so I don't want to drill holes in the ceiling. I didn't purchase their entire setup, just the canopy, reflector and socket. I wanted an electronic ballast, and all they sale are the magnetic ones. So I purchased 2 Ice cap electronic ballasts and wired everything myself. It wasn't a hard project to do. If you need any help, just email me or you can post here.
