Need A Really Quick Response!

i buying this this 30 inch double tube lighting system and i was wondering what length bulbs does it take? Im using that system plus a single tube lighting system for a 30 gallon aquarium over a glass hood and under a black canopy, do you think the 2 light strips will fit with out covering the feeding strip over the glass top?

A guess after looking at it would be 24"/ 20 watt tubes, the canopy is 30" so the next size tube down would be 24".
