sps in a 20g with 130w pc lights?

[lakshwadeep]

I really want to grow some sps corals in my 20g tank. The lighting is a 2x65w Coralife aqualights power compact (6.5 WPG). However, since wattage per gallon is not a totally accurate indicator of what I can grow, I'm wondering if I can grow some acroporas or montiporas.

 

Should I place them close to the lights (e.g. less than 10" from the top)? Or is it feeding/mineral supplements that determines what I can get? If you have other coral suggestions (soft corals, lps), your welcome to post them, also.

 

Thanks for your input.
