Looking for LPS or Soft Coral Frags

[BCReefer]

Everyone that I spoke to told me that with my simple lighting that I could not get any frags so I was looking at getting 4 – 5 fish and a clean up crew with 2 cleaner shrimp. I am adding equipment in stages or I would end up in divorce court. When I look at my aquarium I feel something is missing. With only LR and the fish, it seems so empty. I would love to add some frags, they would add so much. How much LR can I have a 27 G? I have approximately 22 lbs now with lots of room left over.

Thanks for all the help.
