Can I use the 24w T-5 lighting that came with my 29 nano and put corals in there? One is a 12w white bulb and the other is a 12w actinic
I wouldn't. You might be able to get away with some mushrooms or GSP up top, but those lights just won't be able to sustain the corals long term IMO. The colors won't be very bright, growth will be slow etc. Almost as if the corals were in limbo.
cloak, what about an anemone under my lights? Would that be okay?
No.. These tend to require the bright lights as well plus a pretty stable environment too. If you want to create a happy healthy reef aquarium keep in mind that having the proper lighting will be key. I know they can be expensive and all, but if your in this for the long haul then it's definitely worth it.
Just as an example, for a 29 gallon tank something like a Kessil A160WE be a good choice. They're not very expensive, they don't generate a lot of heat, you'll be able to adjust both the whites & the blues to achieve the look you want, they're easy to mount etc. You should be able to keep pretty much anything in the tank with this set up.

That is expensive!! I am in it for the long run but I might not be with the tank I have. I would like to upgrade the tank in 6 months when i move out. Maybe I will stick to FOWLR for the time being and then upgrade lights and the tank in the future. BUT what do you think about the Mars Aqua 165w LED Unit?
