Yes it is! Check the pictures in my signature, the 36 gallon bowfront. That is a 30" Fugeray about 20" off the substrate. At 24" that you have the light might be getting a little too low (17 par) except for low light plants. The tall stuff will grow fine, the little stuff close to the 'dirt' will be very slow.
The are coming out with a 30" Ray2 (DD, 7K daylight in 2 rows) , any time now I think (Lowe will answer on here soon, he is the factory rep) You might need to inject Co2 to avoid algae with that, or hang/shade it.
PS: No Actinics in a Fugeray, 7k whites and a few blue moonlights.
