New lights for my nano reef

[Hawk23]

I am planning on switching the light fixture on my 20 gallon long nano reef. I previously had a 2x65 watt pc system. I now plan to jump to a nova extreme t5 system. the particular model I am looking at is the 30" fixture: 2x24 watt t5HO. I have previoulsy done softies and some lps with success. Would I be able to do SPS now? I am just looking for a variety of opinions. My tank's
dimensions are 30"x12"x12". My water movement is as follows: 200gph marineland filter and a 240gph koralia nano pump. I am fairly new into the coral part of saltwater aquariums(9months), so any advice would be helpful. thanks.
