No need for a UV

should do the job.
I am assuming this tank is not drilled. You could also look into an overflow and the idea of going with a sump style filter. There are some DIY

Basic requirements at this time would include:
Good protein skimmer(recommended, but not required)
for water flow.
Lighting (If using LR

to promote coraline growth)
research(you are doing that now)
Most of all patience lots of patience
Check out the suggested reading lists as well. Fenner's book "The Conscientious Marine aquarist is one of the best. You can pick up used copies for under $20.
