How many watts per gallon should I have on a black water south American tank? It would have swords, valls and moss.

I have a t5 I was using on my 55g, not sure whats the watts are. Ill look later and see.

I'd shoot for 1.5-2.0 wpg of light. Swords and vals grow up to the surface so they'll get plenty of light and since moss doesn't require much 1.5-2.0 should help you avoid algae issues.
