I have 4-24" T5's running on 2 ballasts. When i move them to my new tank i plan on running 2-36" bulbs because thats the only thing i can fit. Can i run the 36" bulbs on the old ballasts? if so do i need to use 1 ballast for each bulb, or can one of the ballasts run both bulbs? I'll go get the number off the ballast if i have to, but it's kind of a pain to get to. thanks
