Coralife PC fixture

[Buddyboy]

Hi All,

I have a 20" Coralife Aqualight fixture on my 10G that I would like to put on top of a new 20G tank (24" long). If I was to buy Aqualight legs for it, would they extend 2 inches on each side and allow me to put my 20" hood on a 24" tank? I would rather do this then just lay the fixture right on my glass versa-hood as I would be concerned about the glass cracking and the fixture falling into the tank! If it won't work, can you think of any other way to do this? Thanks so much for your help!

Bud
